"Where - (a) any part of the tax determined under this regulation is not paid within 30 days from the date on which the determination became final and conclusive, and (b) the Board are of the opinion that an employee in respect of whose emoluments the determination was made has received his emoluments knowing that the employer has wilfully failed to deduct the amount of tax which he was liable to deduct under these Regulations from those emoluments, the Board may direct that such part of that tax as it appears to them should have been but was not deducted under these Regulations by the employer on payment of the relevant emoluments shall be recovered from the employee, and, where the Board so direct, the employer shall not be liable to pay that part of that tax to the collector."
"If it appears to the Board that the amount specified in regulation 40(2) or 41(2) which the employer is liable to pay to the collector exceeds the amount actually deducted by him from emoluments paid during the relevant income tax period and the Board are of the opinion that an employee has received his emoluments knowing that the employer has wilfully failed to deduct the amount of tax which he was liable to deduct under these Regulations from those emoluments, they may direct that the amount which they consider to constitute the excess ("the excess amount") shall be recovered from the employee, and, where the Board so direct, the employer shall not be liable to pay the excess amount to the collector."
"Any tax which is payable to the collector under - (a) regulation 101(2) ... shall be payable within 14 days of the date on which the collector first makes application for its payment."
"Any tax which is payable to the collector by any employee may be recovered in the manner provided by the Income Tax Acts."
"(1) Tax due and payable under any assessment may ... be sued for and recovered from the person charged therewith as a debt due to the Crown by proceedings in a county court commenced in the name of a collector."
"The Board of Inland Revenue take the view that a director by virtue of his offices has the responsibility for management which amongst other things requires that he ensures that the Company complies with its statutory obligations under the Income Tax Regulations and implies that he should ensure that PAYE is correctly operated on his own remuneration and he cannot abrogate responsibility to any other person."
"... the word 'knowing' means what it says and does not mean 'ought to have known' or 'should have been suspicious' or any other weakening of knowledge."
"The principle underlying those decisions, [ O'Reilly v Mackman[1983] 2 AC 237 and Cocks v Thanet District Council[1983] 2 AC 286 ], as Lord Diplock explained in O'Reilly , is that there is a 'need, in the interests of good administration and of third parties who may be indirectly affected by the decision, for speedy certainty as to whether it has the effect of a decision that is valid in public law.' The main argument urged on behalf of the appellants was that this is a typical case where there is a need for speedy certainty in the public interest. I accept, of course, that the decision in this appeal will indirectly affect many third parties including many of the appellants' tenants, and perhaps most if not all of their ratepayers because if the appellants' impugned decisions are held to be invalid, the basis of their financial administration since 1981 will be upset. That would be highly inconvenient from the point of view of the appellants, and of their ratepayers, and it would be a great advantage to them if persons such as the respondent who seek to challenge their decision were limited to doing so by procedure under Order 53. Such procedure is speedy and avoids prolonged uncertainty about the validity of decisions. An intending applicant for judicial review under Order 53 has to obtain leave to apply, so that unmeritorious applications can be dismissed in limine and an application must normally be made within a limited period of three months after the decision which has impugned [sic], unless the court allows an extension of time in any particular case. Procedure under Order 53 also affords protection to public authorities in other ways, which are explained in O'Reilly and which I need not elaborate here. It may well be that such protection to public authorities tends to promote good administration. But there may be other ways of obtaining speedy decisions; for example in some cases it may be possible for a public authority itself to initiate proceedings for judicial review. In any event, the arguments for protecting public authorities against unmeritorious or dilatory challenges to their decisions have to be set against the arguments for preserving the ordinary rights of private citizens to defend themselves against unfounded claims. It would in my opinion be a very strange use of language to describe the respondent's behaviour in relation to this litigation as an abuse or misuse by him of the process of the court. He did not select the procedure to be adopted. He is merely seeking to defend proceedings brought against him by the appellants. In so doing he is seeking only to exercise the ordinary right of any individual to defend an action against him on the ground that he is not liable for the whole sum claimed by the plaintiff. Moreover he puts forward his defence as a matter of right, whereas in an application for judicial review, success would require an exercise of the court's discretion in his favour."
"They [these suggestions] do involve not only considering the technical questions of the distinction between public and private rights and bodies but also looking at the practical consequences of the choice of procedure which has been made. If the choice has no significant disadvantages for the parties, the public or the court, then it should not normally be regarded as constituting an abuse."
"... as in Roy's case, I would regard this as being a case where the plaintiff's relationship with a public body whether statutory or contractual would confer on him conditional rights to payments so that bringing of ordinary actions to enforce those rights was not in itself an abuse of process"
"The present case is clearly not one of a collateral attack on a previous decision; indeed, in both actions Oceanus are not plaintiffs but defendants. Any analogy with the foregoing cases therefore breaks down in limine."
