Business Rates - Billing Authority's Disclosure Obligations

Where a Local Authority (Billing Authority) has applied by way of complaint (the 'Complaint'), to the Magistrates Court, for a national non-domestic rates (Business Rates) liabilty order ('BRLO') against an alleged ratepayer, and the Complaint is opposed/defended as liability is in dispute, is the Billing Authority under any duty of disclosure during the course of the proceedings? and, if so, what is the scope of that duty?

This article will consider this issue of disclosure, in light of the recent judgment in Total Sprint Ltd v Swale BC [2023] EWHC 2968 (Admin); [2024] 1 WLR 1687 ('Total Sprint'), a decision of Eyre J on 19.11.23. Readers short on time can jump straight to the heading 'Duty of Disclosure' below.

Standard Directions

Where a Billing Authority has applied by way of complaint, to the Magistrates Court, for a BRLO, the Magistrates Court will issue a summons, requiring the alleged ratepayer/defendant to attend a court hearing '...to show why he has not paid the sum which is outstanding' (reg.12(2) Non-Domestic Rating (Collection and Enforcement) (Local Lists) Regulations (SI 1989/1058) (the ‘1989 Regulations’)). Assuming the Complaint is opposed/defendant, and unless the Complaint is simply adjourned[1], the Magistrates Court is likely to make directions with a view to preparing the Complaint for a contested final hearing (outside the bulk application list). Directions might include directions that (sequentially):

(1) Billing Authority do file and serve the relevant demand notices, reminder notices and any final notices [not always specified as a separate direction]

(2) Defendant do file and serve its evidence in opposition to the Complaint [since the alleged ratepayer bears the initial evidential burden of justifying why it has not paid]

(3) Billing Authority do file and serve its evidence in response to the Defendant's evidence

(4) Defendant, if so advised, do file and serve its evidence in reply [not always directed]

Further, there will typically be directions for

(5) the preparation of a index paginated contested hearing bundle, and

(6) skeleton argument to be lodged at Court and exchanged between the parties (parties' advocates), and

(7) the Complaint will be listed for a contested hearing.

Standard directions for parties to file and serve their evidence, like those above, leaves open the question of quite what, if any, duty of disclosure a Billing Authority owes to the defendant/alleged ratepayer.

Total Sprint

While not essential to understanding the duty of disclosure, it is convenient to note a few of the facts from Total Sprint. In Total Sprint:

(1) Swale BC, as the relevant Billing Authority, applied by way of complaint to the Magistrates Court, for a BRLO against an alleged ratepayer Sprint Couriers (Southern) Ltd ('Couriers'), in respect to certain units on a trading estate (the 'Units') and liability periods 1.4.15 to 1.4.19 ('LPs 2015-2019');

(2) on 9.10.17 and 30.7.18, the Magistrates Court made the BRLOs against Couriers as sought (the 'Couriers BRLOs') (paragraph 4);

(3) on 9.9.19, the Billing Authority issued and sent to Couriers, demand notices for the (same) Units and for the (same) liability period LPs 2015-2019, but with zero balances (paragraph 4);

(4) on 12.9.19, the Billing Authority issued and sent demand notices to Total Sprint for the (same) Units for the (same) liability period LPs 2015-2019[2];

(5) on 13.1.20, the Billing Authority applied by way of Complaint to the Magistrates Court, for a BRLO against the alleged ratepayer Total Sprint, for the (same) Units and for the (same) liability period LPs 2015-2019. In that application, the Billing Authority did not disclose to the court the events described at (1) to (3) above (a breach of the Billing Authority's duty of candour[3]);

(6) In the normal way, in response, the Magistrates Court summoned the Total Sprint '...to show why he has not paid the sum which is outstanding' (reg.12(2) of the 1989 Regulations). At the first hearing, the Court prospectively moved the Complaint out of the bulk applications list and gave directions (by consent), including a direction that: 

'...the Council should ... conduct a search as if CPR 31.7 applied and should disclose the documents on which it relied together with those which adversely affected its case and those which supported Total Sprint's case.' (paragraph 105)

(7) Subsequently, the DJ held that the Billing Authority had '...had a duty of disclosure which it had broken.' (paragraph 106) (the duty arising from the court order but also existing anyway), in that the Billing Authority had failed '...to conduct a search for documents adverse to its case and/or supportive of Total Sprint's position.' and in particularly, had failed to disclose:

(a) '...the Couriers Liability Orders'

(b) 'the email exchanges between Mr Prior and Mr Mason' (which '...were relevant to the question of whether Total Sprint had been in occupation of the Units' (paragraph 24); Mr Prior being the Billing Authority's Rating Officer; and Mr Mason being, it seems, an agent for Couriers (paragraph 24));

(c) 'the records of Mr Prior's observations at the trading estate.' (paragraph 106)[4].

These failings formed part of a wider submission by Total Sprint, that these and other Billing Authority failings (for instance, breach of duty of candour to Magistrates Court when requesting a summons; collateral attack on existing BRLO/attempt to re-litigate a concluded issue[5]), meant that the DJ should set aside, or stay, the summons (in effect, the Complaint) as an abuse of process (paragraph 9). The DJ refused to set aside or stay the summons (paragraph 9), and subsequently made a BRLO against Total Sprint. Total Sprint then appealed, by way of Case Stated, that decision, particularly, certain component decisions/findings that led to the imposition of that BRLO[6].

Duty of Disclosure

Under the heading 'The Council's Disclosure Duty: what was the extent of the Duty...', Eyre J made a number of points:

(1) the disclosure provision in the Civil Procedure Rules ('CPR'), particularly Part 31 of the CPR, does not, without more, apply to BRLO Complaints (paragraph 105); but

(2) '...the Council had an obligation to disclose potentially adverse material once it knew that liability was being put in issue.'  (paragraph 109);

(3) The disclosure obligation set out in (2) above is not dependent on the Magistrates Court making an order for disclosure. While the Magistrates Court in Total Sprint had made a direction for the Billing Authority to conduct a search as if CPR 31.7 applied, and to disclose the documents on which it relied, together with those which adversely affected its case and those which supported Total Sprint's case (paragraph 105), this was not the source of the underlying disclosure obligation on the Billing Authority (paragraph 106). In other words, Billing Authorities are under an obligation (a duty[7]) to disclose to defendant/alleged ratepayers, potentially adverse material to the Billing Authority's case, once it knows that liability is in dispute; no court order or direction to that effect, is required[8].

(4) Eyre J agreed[9a] with the 1st instance DJ's judgment that 'the imperative of fairness and the needs of natural justice "required the parties to approach the issue as if standard disclosure under the CPR applied to these proceedings".' (paragraph 106). Eyre J said 'This was, indeed, an aspect of the requirement of fairness.' (paragraph 109). Eyre J referred to Newman v Commissioner of the Metropolitan Police [2009] EWHC 1642 (Admin) ('Newman'), wherein Richards LJ 'emphasised that the question was to be governed by "the imperative of ensuring fairness in the proceedings" [35]...'[9b].

(5) if disclosure were not so required, there would be a '...risk that the Magistrates Court will be misled' (paragraph 109).

(7) it is the duty of the Billing Authority to 'disclose such material' (paragraph 109), though it will '...ultimately be a matter for the court whether the material was in fact adverse to the [Billing Authority's] case and whether it should be admitted in evidence...' (paragraph 109);

Eyre J said his view was 'reinforced' (paragraph 109) by two observations:

(a) the Billing Authority was a public body acting as such to enforce a tax liability; and

(b) certain pieces of information can be, in essence, naturally just in the knowledge of a Billing Authority. Eyre J said 'just as questions of rateable occupation were peculiarly within the knowledge of the ratepayer so questions of the previous proceedings taken by the Council and of the communications with the Council were peculiarly within that body's knowledge.' (paragraph 109)

Scope of the Duty of Disclosure

In determining the scope of the duty of disclosure, requirement of fairness underlies the analysis. Eyre J:

(1) made reference to Newman, and to the fact that Richards LJ in Newman had:

(a) taken '...a restrictive view of the material which had to be disclosed in the circumstances of that case.' (paragraph 109); and

(b) found that '...although fairness did not require "wholesale disclosure" of the source material underlying the statement of a particular police officer it did require disclosure of material known to undermine the police commissioner's case or to assist the other party [37].' (paragraph 109)[10].

Fairness therefore, for the case before Richards LJ in Newman, required disclosure of two types of material; material which:

(a) undermined the Billing Authority's case; or

(b) assisted the defendant/alleged ratepayer.

To a degree, these two types of material can be seen as two sides of the same coin. Material that undermines the Billing Authority's case is likely to assist the defendant/alleged ratepayer, and vice versa[11].

(2) held, in effect, that the requirement of fairness in business rates cases, required that the Billing Authority be subject to an'...obligation to disclose potentially adverse material' (paragraph 109). At first blush, this would seem to raise a question of whether this obligation is the same as that found to arise in Newman, on the facts in Newman. However, in the author's view, the tenor of Eyre J's judgment is that Eyre J intended the scopes of each to be the same (co-extensive and coterminous). If that is correct, then the scope of the Billing Authority's duty of disclosure in business rates cases - is to '...disclose potentially adverse material' (paragraph 106), which in turn, breaks down into an obligation to disclose material which:

(a) undermines the Billing Authority's case; and/or

(b) assists the defendant/alleged ratepayer.

(3) agreed with the DJ's view at first instance, that 'the imperative of fairness and the needs of natural justice "required the parties to approach the issue as if standard disclosure under the CPR applied to these proceedings".' (paragraph 106). 'Standard disclosure' is a defined term in the CPR; CPR r.31.6 is entitled 'Standard disclosure—what documents are to be disclosed' and it provides:

'Standard disclosure requires a party to disclose only-

(a) the documents on which he relies; and

(b) the documents which—

(i) adversely affect his own case;

(ii) adversely affect another party’s case; or

(iii) support another party’s case; and

(c) the documents which he is required to disclose by a relevant practice direction.'

CPR r.31.6 (a), (b)(ii) and (c) can be ignored for present purposes, leaving (b)(i) and b(iii)[12], which are in substance, very similar to those stated to apply in Newman.

The Scope

Bringing these 3 aspects together, it seems clear that, in business rates cases in the Magistrates Court where liability has been put in dispute, the requirements of fairness (and the needs of natural justice), require the Billing Authority to disclose to the defendant/alleged ratepayer, material it has which:

(a) undermines the Billing Authority's case/adversely affects the Billing Authority's case; and/or

(b) assists/supports the defendant/alleged ratepayer's case.

Breach of the Duty of Disclosure

Where a Billing Authority fails to comply with its duty of disclosure, there is a risk that the Magistrates Court will be misled, because the evidence before it will not be all the evidence it could, and should, have before it, upon which to make a determination. Such a situation would be unfair.

On the facts in Total Sprint, the Billing Authority had breached its duty of disclosure. It had:

(a) failed '...to conduct a search for documents adverse to its case and/or supportive of Total Sprint's position' (paragraph 106); and

(b) failed to disclose:

(i) the Couriers Liability Orders (paragraph 106);

(ii) the email exchanges between Mr Prior and Mr Mason; and

(iii) the records of Mr Prior's observations at the trading estate.

The upshot from the failure to comply was that this '...meant that there was a risk of the court being misled.' (paragraph 109) (though, in the event, the disclosure was later brought before the Magistrates Court: 'all the material ultimately being available to the court' (paragraph 110))

As to this material which was not properly disclosed by the Billing Authority, Eyre J said, that '...the material in question...clearly was at least potentially adverse to the [Billing Authority's] case.' (paragraph 110). Eyre J said, at paragraph 110:

'The fact that the [Billing Authority] had previously taken the view that a company other than Total Sprint was the rateable occupier was at least potentially a factor in favour of Total Sprint's contention that it was not the occupier.

Consequently, Eyre J said, at paragraph 110: It follows that the material should have been disclosed and that the [Billing Authority] was in breach of its duty in not doing so.'

Non-compliance with duty of disclosure

Is a Billing Authority's failure to comply with its duty of disclosure, an abuse of process, such that the Complaint can be, and ought to be, dismissed/summons set aside or stayed? It is understandably to think that it might. Breaching an '...obligation to disclose potentially adverse material' will, after all, likely advantage the breaching party to the disadvantage of the innocent party. On this question, Eyre J held that, such a breach will not typically be seen as an abuse of process ('...a failure to make proper disclosure will not typically be seen as an abuse of process.' (paragraph 110)). Drawing on the approach adopted by the CPR in respect to non-compliance with disclosure obligations, it more usually is characterised non-compliance of the rules - for which the court can, in consequence, impose unless order and costs orders, with the innocent party given adequate time to consider the documents, when they are eventually produced. Eyre J said, at paragraph 110:

'In civil litigation governed by the CPR such a failure would be seen as a failure to comply with the rules rather than abuse. The remedy for such a failure would typically be costs orders; adjournments to give the other party an opportunity to consider the documents; and potentially unless orders. In effect the failure would be addressed through the trial process. [Counsel for the Total Sprint] was right to emphasise that this was what happened here .'

On the facts in Total Sprint, as the material had ultimately been made available to the Magistrates Court, no further non-compliance linked sanction/consequence was needed. Further, Eyre J held that the DJ had correctly held that the Billing Authority's failure had not itself amounted to an abuse of process.

I will consider below whether it was to be seen as such when considered together with the other failings of the [Billing Authority].'

Duty of Disclosure on Defendant/Alleged Ratepayer

While not the focus of this article, reader may have noticed that Eyre J in Total Sprint seemingly agreed with the 1st instance DJ's judgment that 'the imperative of fairness and the needs of natural justice "required the parties to approach the issue as if standard disclosure under the CPR applied to these proceedings".' [bold added] (paragraph 106). In other words, that both parties - the Billing Authority and the defendant/alleged ratepayer, were under a duty of disclosure to the other, as if standard disclosure under the CPR applied to the proceedings. Though the Billing Authority's counsel in Total Sprint made the point/submission that Total Sprint had 'not itself made any disclosure and had thereby failed to disclose documents which might be relevant to the issues and which might have been adverse to its case...' (paragraph 108), the issue of whether a defendant/alleged ratepayer was under a co-extensive and coterminous duty of disclosure was not really explored in Total Sprint.

Summary

A Billing Authority owes a duty of disclosure to a defendant/alleged ratepayer, when pursuing a Business Rates Complaint in the Magistrates Court where liability is put in dispute[13]. That duty exists whether or not the Magistrates Court has made a direction to that effect. The underlying basis for the duty is not contained in any statutory regime, but is founded upon the general imperative of ensuring the proceedings were fair, and the needs of natural justice. The duty of disclosure consists of an '...obligation to disclose potentially adverse material' (Total Sprint, paragraph 109) / duty to give standard disclosure, as if CPR r.31.7 applied. This in turn, breaks down into an obligation to disclose material to a defendant/alleged ratepayer which:

(a) undermines the Billing Authority's case/adversely affects the Billing Authority's case; and/or

(b) assists/supports the defendant/alleged ratepayer's case.

[1] And also assuming the Magistrates Court does not simply adjourn the Complaint to another bulk application list hearing date

[2] Later revised to 16.4.15 (but this is immaterial for present purposes)

[3] Another issue in Total Sprint Ltd v Swale BC [2023] EWHC 2968 (Admin); [2024] 1 WLR 1687 was whether the Billing Authority had complied with its duty of candour to the Magistrates Court when it had applied by way of complaint to the Magistrates Court, and, importantly, requested the Magistrates Court issue a summons against the alleged ratepayer.

[4] In Total Sprint Ltd v Swale BC [2023] EWHC 2968 (Admin); [2024] 1 WLR 1687, Eyre J said, at paragraphs 21 and 27:

'The District Judge ...identified the following issues:

...

Issue (5): Did the complainant fail to comply with a duty of disclosure to the respondent by not disclosing the fact of the Sprint Couriers liability orders and relevant correspondence concerning occupation of the premises?

...

At [167] the District Judge set out the findings of fact in relation to matters other than the question of rateable occupation. He noted again the Council's failure to disclose the Couriers Liability Orders; its failure to search for documents adverse to its case or supportive of Total Sprint's case; the Council's possession of documents adverse to its case and/or supportive to that of Total Sprint and which it did not disclose; and the giving by Mr Prior of untruthful evidence.'

[5] In Total Sprint Ltd v Swale BC [2023] EWHC 2968 (Admin); [2024] 1 WLR 1687, Eyre J set out his judgment on these issues, at:

(1) paragraphs 94 to 104, under the heading 'A Duty of Candour: did the Council owe such a Duty and if so was there an abusive Breach of the Duty?'

(2) paragraphs 79 to 93, under the heading 'Were the Proceedings against Total Sprint abusive as a Collateral Attack on the Couriers Liability Orders?'

The answers to the Case Stated Questions posed, which are not exactly worded the same as these titles, but similarly, are at paragraph 123.

Answers:

'The District Judge was right to conclude that the Council owed a duty of candour to the court at the time of applying for the issue of the summons but he was wrong as to the scope of that duty which did not require disclosure at that time of the existence of the Couriers Liability Orders.' (paragraph 123(3)(a))

'No: the District Judge was wrong to conclude that the application for a liability order was a collateral attack on the Couriers Liability Orders.' (paragraph 123(3))

[6] In Total Sprint Ltd v Swale BC [2023] EWHC 2968 (Admin); [2024] 1 WLR 1687, Eyre J summarised the 1st instance DJ's decision, at paragraph 9:

'...in essence the District Judge found that the [Billing Authority's] actions had amounted to abuse; concluded that on balance the summons was not to be stayed; proceeded on the footing that the burden of establishing that it was not in rateable occupation (and so not liable for the sums demanded) fell on Total Sprint as ratepayer; found that Total Sprint had failed to discharge that burden; and as a consequence concluded that the liability order was to be made.'

[7] The words 'duty' and 'obligation' can be used interchangeably here.

[8] In Total Sprint Ltd v Swale BC [2023] EWHC 2968 (Admin); [2024] 1 WLR 1687, Eyre J said, at paragraph 109:

'I agree with the District Judge that regardless of the court order the Council had an obligation to disclose potentially adverse material once it knew that liability was being put in issue.'

[9a] Eyre J in Total Sprint Ltd v Swale BC [2023] EWHC 2968 (Admin); [2024] 1 WLR 1687 makes it clear that he agrees with the DJ's approach, in paragraph 123 of Eyre J's judgment, where he answered the following question, in the following way:

Question: 'Was I correct to conclude that the [Billing Authority] owed:...b. a duty of disclosure and, if so, was I correct as to the scope of that duty?' (paragraph 43(4))

Answer: 'Yes: the District Judge was right both as to the existence and the scope of the duty of disclosure during the course of the proceedings.' (paragraph 123 (3)(b))

[9b] In Newman v Commissioner of the Metropolitan Police [2009] EWHC 1642 (Admin), Richards LJ sitting in the Divisional Court (with Teare J) gave judgment in an appeal by way of Case Stated, brought by a defendant in civil proceedings (football banning orders) in the Magistrates Court, against the Justices' decisions to admit into evidence, certain pieces of evidence, without ordering certain other evidence to be disclosed to the defendant. To be more specific, the appeal was against Justices' decisions to grant a police commissioner (the applicant for a football banning order against the defendant) permission to adduce: (1) a compilation witness statement ('Police Statement'); and (2) compilation disc containing video evidence ('Disc'). At first instance, the defendant had opposed the granting of such permission, on the grounds that underlying evidence that formed the basis of both the Police Statement and Disc contents, had not been disclosed to the defendant.

The Justices held that there was no statutory regime directly applicable to disclosure in civil proceedings in the Magistrates Court, so it was appropriate to consider the issue on the general imperative of ensuring the proceedings were fair.

In the Divisional Court, Richards LJ said, at paragraph 34:

'In my judgment, the justices were plainly correct to proceed on the basis that there are no directly applicable disclosure requirements in relation to an application for a football banning order under section 14B. These are civil proceedings, and the rules relating to disclosure of unused material in criminal proceedings do not apply to them. The disclosure provisions of the CPR do not apply to magistrates' courts, as was observed in Cleary. There are specific statutory provisions and rules governing the admission of hearsay evidence, but there are none laying down any particular disclosure regime.'

(The reference to Cleary in the above quotation, is a reference to R (Cleary) v Highbury Corner Magistrates' Court [2007] 1 WLR 1272)

Consequently, with no directly applicable disclosure rules in civil proceedings in the Magistrates Court, Richards LJ said, at paragraph 35:

'...the justices were correct to approach the matter by reference to the imperative of ensuring fairness in the proceedings before them...'

[10] Though not quoted by Eyre J in Total Sprint Ltd v Swale BC [2023] EWHC 2968 (Admin); [2024] 1 WLR 1687, in Newman v Commissioner of the Metropolitan Police [2009] EWHC 1642 (Admin), Richards LJ sitting in the Divisional Court (with Teare J) said:

'Fairness did require disclosure of anything known to undermine the Commissioner's case or to assist the appellant's case...' (paragraph 37)

However 'I do not think that fairness can be said to have required wholesale disclosure of the source material underlying PC Davies' first witness statement.' (paragraph 37)

[11] Given evidence is needed only on the issues in dispute (because admitted facts don't require evidence for them; and no other fact establishment mechanism seems engaged), and where each side will, by definition, be contending different things, these two aspects of disclosure will usually be just two sides of the same coin.

[12] The main textbook on the Civil Procedure Rules ('CPR'), is known as the 'White Book'. In the 2024 Ed. of the White Book, accompanying the CPR themselves, is commentary. The commentary to CPR r.31.6 (entitled 'Standard disclosure—what documents are to be disclosed') contains, at paragraph 31.6.2, commentary under the heading entitled "adversely affect"; "support", which reads:

'There are no definitions of “adversely affect” or “support”. In determining the issues in a party’s case the statements of case are an essential reference point: Harrods Ltd v Times Newspaper Ltd [2006] EWCA Civ 294; [2006] All E.R. (D) 302 (Feb) at [12]. A document which of itself does not “adversely affect” a case, but which may provide lines of inquiry leading to other information having a negative effect, is not covered by this provision. Adverse effect is normally primarily assessed by reference to the material allegations in the statements of case. However there is nothing in the CPR to restrict the concept in this manner, and a document casting doubt on the credibility of a party whose own evidence was important could be seen as one “adversely affecting” that party’s case: Hedrich v Standard Bank London Ltd [2008] EWCA Civ 905. Parties probably do not need to give disclosure of documents relating to non-material allegations in pleadings, i.e. those which even if substantiated would not affect the result. The confidentiality of a particular document does not of itself justify non-disclosure: see Science Research Council v Nasse [1980] A.C. 1028 and 31.3.36 above. Masking irrelevant parts of a document by way of redaction is in principle possible under r.31.6 but care must be taken, as the deletion of parts that are relevant could give rise to a specific disclosure order under r.31.12: Tullett Prebon Group Ltd v Davis [2007] EWHC 2739. In Serious Organised Crime Agency v Namli [2011] EWCA Civ 1411; [2012] C.P. Rep. 10; [2013] 1 Costs L.O. 17, the Court of Appeal rejected the submission that the words “as against another party” should be read into r.31.6(b)(ii) so as to limit the disclosure obligation imposed by that provision to documents which adversely affected another party’s case as against some party other than the disclosing party.

Documents which relate purely to cross-examination as to credit and to no other issue in the trial are outside the scope of standard disclosure: Favor Easy Management Ltd v Wu [2010] EWCA Civ 1630, [2011] 1 W.L.R. 1803.

In Shah v HSBC Private Bank (UK) Ltd [2011] EWCA Civ 1154 the Court of Appeal stated that it was dangerous to apply RSC authorities as to the test of relevance under the old rules to the CPR test of standard disclosure, particularly as there was no express test of “relevance” in CPR r.31.6. The Court of Appeal further held that standard disclosure would not cover documents revealing the identity of a party’s employees, which information at most went to a general testing of a party’s case rather than to a positive case put by the other party. Such material was train of inquiry material subject to discovery under the RSC, but not standard disclosure under the CPR.'

[13] In Total Sprint Ltd v Swale BC [2023] EWHC 2968 (Admin); [2024] 1 WLR 1687, Eyre J said, at paragraph 92:

'If Total Sprint had adduced evidence putting the fact of rateable occupation in issue then the Council would have been obliged to disclosure the Couriers Liability Orders. It would have had to do so even without the disclosure order which was made. However, that obligation was an aspect of ensuring that the conduct of the proceedings was fair. Indeed, it demonstrates how the trial process could operate to ensure a fair hearing of such issues as were in due course raised by Total Sprint. The issue in the current proceedings would, if Total Sprint had satisfied the evidential burden of raising it, have been whether Total Sprint was in rateable occupation of the Units at the relevant times.'
