"13. - (1) An employer shall not make a deduction from wages of a worker employed by him unless- (a) the deduction is required or authorised to be made by virtue of a statutory provision or a relevant provision of the worker's contract, or (b) the worker has previously signified in writing his agreement or consent to the making of the deduction. (2) In this section "relevant provision", in relation to a worker's contract, means a provision of the contract comprised- (a) in one or more written terms of the contract of which the employer has given the worker a copy on an occasion prior to the employer making the deduction in question, or (b) in one or more terms of the contract (whether express or implied and, if express, whether oral or in writing) the existence and effect, or combined effect, of which in relation to the worker the employer has notified to the worker in writing on such an occasion. (3) Where the total amount of wages paid on any occasion by an employer to a worker employed by him is less than the total amount of the wages properly payable by him to the worker on that occasion (after deductions), the amount of the deficiency shall be treated for the purposes of this Part as a deduction made by the employer from the worker's wages on that occasion."
"14. - (1) Section 13 does not apply to a deduction from a worker's wages made by his employer where the purpose of the deduction is the reimbursement of the employer in respect of- (a) an overpayment of wages, or (b) an overpayment in respect of expenses incurred by the worker in carrying out his employment, made (for any reason) by the employer to the worker. … … … (5) Section 13 does not apply to a deduction from a worker's wages made by his employer where the worker has taken part in a strike or other industrial action and the deduction is made by the employer on account of the worker's having taken part in that strike or other action."
"If the employees raise a dispute as to whether or not they were available for work that factual issue requires resolution before it is possible to identify whether the deduction was lawful. Accordingly, on that issue the appropriate course of action for the tribunal would be to proceed to hear the merits of the claim."
"Once an employer makes a deduction on account of a worker having taken part in a strike or other industrial action, we found it impossible to see how the exception can be of any effect unless it covers at a basic level whether the employee took part in the action in question."
"it would not be possible to embark on an investigation into those facts without trespassing into exactly the area where Parliament has decided the Employment Tribunal should not be involved. The lawfulness of a deduction made as a result of industrial action is clearly to be resolved in the County Court."
"If the worker believes that a deduction is not contractually authorised, his means of redress is the civil court for breach of contract, rather than an industrial tribunal. Such contentious and difficult problems where, as the Committee knows, emotions occasionally run high are best dealt with by the courts not industrial tribunals. Therefore deductions made as a result of industrial action should be separated from those deductions about which a complaint may be made to an industrial tribunal."
"heard no evidence and made no findings of fact."
"Section 1(5) [now section 14 of the 1996 Act] disapplies the provisions of section 1(1) [now section 13 of the 1996 Act] in cases where there is 'any deduction' lawful or unlawful, falling within the specified categories. In those cases the Industrial Tribunal have no jurisdiction to enquire into or determine the issue of lawfulness or unlawfulness of the deduction…"
"If the section, section 14 is an exemptive section, it must be an exemption from something that otherwise falls within the generality of the provision within which it is an exception" (paragraph 22). He considered it was wholly unnecessary and contrary to the clear intention of the statute to read the word "lawful" into section 14(5). Citing Browne-Wilkinson P in Courtaulds Northern Spinning Limited v Moosa[1984] ICR 218 , 224/5 , Burton P stated that Parliament intended "to prevent [Employment] Tribunals from going into the merits or demerits of collective industrial action" (paragraph 23). He rejected the argument that the employer could have enquired into the deduction in that case without going into the merits or demerits or the nature or extent or indeed the duration of the industrial action in question. The Appeal Tribunal was not persuaded of this without knowing the full facts. The decision before it was (paragraph 25): "… not a decision which depends on the particular facts of a given case, but upon a construction of the statute; and what section 14(5) does is to remove this question from the ambit of the Employment Tribunal. One can entirely see, that, in the ordinary case, or the majority of cases, in order to resolve the issue whether there was an appropriate deduction – if appropriate is the right word – made by an employer in respect of an employee who had taken part in industrial action, questions will inevitably arise as to the extent of the action its nature and its duration, how far the particular employee was involved in it, whether he or she was only involved for 2 or 3 hours and not the whole day, or whether some part of what he or she was doing may not be described as strike but could be described as something short of a strike. The whole of that area, is, as we see it, plainly ruled out by section 14(5) once the employer shows, as is common ground in this case, that the deduction was made on account of the participation of the employee."
