"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 workers 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."
"6 The Applicant was employed by the Respondent as a senior project control engineer. In or about May 1997, the Applicant commenced an assignment in Georgia and Azerbaijan, working on a pipeline project. The terms of the assignment are set out in two letters, both dated12 May 1997 , one of the letters setting out the details of the assignment and another explaining the basis upon which net overseas pay was to be calculated. Under the terms of the letters, the Respondent would deduct from the Applicant's earnings a sum which was equivalent to the amount of UK income tax which would have been deducted from the Applicant's basic salary had UK income tax been payable. The Respondent also became responsible for all overseas taxes on the full amount of the remuneration. 7 It has been explained by the Respondents and it is part of their case that the scheme was designed to give employees an element of certainty as to the taxes they would have to pay when working overseas. It is intended to equalise earnings between employees working in different countries on the same project under different overseas tax regimes. The deduction of hypothetical UK tax was not dependent upon any actual liability to either UK or overseas tax. 8 It is the Applicant's case that since he doesn't have any UK tax liability for the period in question that the amount deducted as hypothetical tax should have been refunded to him. It is his argument that the letters of assignment that form the basis of the contract between the parties make no provision to the effect that the hypothetical tax will not be refunded and as a result it is the Applicant's case that in failing to refund the amount deducted, the Respondents have made an unlawful deduction. The Respondent's case is simply that under the terms of the contract they were entitled to make the deduction, a matter which is not in dispute and that under the terms of the contract there was no provision for a refund to be made either express or implied."
"10 If there is any doubt as to what is properly payable to a worker the Tribunal must resolve that doubt in order to determine properly whether an unlawful deduction within the meaning of Section 13 has been made. In determining whether a sum of wages was properly payable Tribunals are required to adopt the same approach as other civil courts in a contractual action. [What] we are required to do in a case of this type is to consider the evidence very carefully, including of course any documentary evidence, and then decide what the amount is properly payable to the Applicant and having decided the amount properly payable we must then go on to ascertain whether or not there has been an unlawful deduction. 11 We have been taken to the letters of assignment which form the basis of the contract between the parties. We make the finding that there is no express provision providing for the refund of the amount deducted in respect of a hypothetical tax. We note in particular that in each case the letters of assignment were accompanied by notional tax calculations. We take those notional tax calculations to be an important part of the letters of assignment. The letters of assignment spell out the reason why the hypothetical income tax is being deducted. The notional tax calculations go one step further and provide in our view clarification beyond doubt as to what is to happen in the event of an employee accepting the assignment that is being offered. In particular of course it sets out the gross pay, any additional payments that are due, any deductions that will be made from that salary and of course at the end of the day, importantly, what the net pay will be. The Respondents wish to equalise, so far as it is possible, the pay received by employees doing similar jobs in different parts of the world and for that reason they have introduced this hypothetical tax system. 12 We have looked in vain for any express provision which provides for the refund of this hypothetical deduction. Similarly we find ourselves unable to find any implied grounds for refunding the amount deducted under the hearing of hypothetical tax deduction. In those circumstances it is our unanimous decision that there has not been an unlawful deduction from the Applicant's wages and the complaint is dismissed."
