“(1) Proceedings on a complaint within section 120 may not be brought after the end of— (a) the period of 3 months starting with the date of the act to which the complaint relates, or (b) such other period as the employment tribunal thinks just and equitable. (2) Proceedings may not be brought in reliance on section 121(1) after the end of— (a) the period of 6 months starting with the date of the act to which the proceedings relate, or (b) such other period as the employment tribunal thinks just and equitable. (3) For the purposes of this section— (a) conduct extending over a period is to be treated as done at the end of the period; (b) failure to do something is to be treated as occurring when the person in question decided on it. (4) In the absence of evidence to the contrary, a person (P) is to be taken to decide on failure to do something— (a) when P does an act inconsistent with doing it, or (b) if P does no inconsistent act, on the expiry of the period in which P might reasonably have been expected to do it.” 34. Mr Emslie submitted that section 123 governed both aspects of the Tribunal’s essential approach to this question of the reasonable adjustments claim and the time limits for bringing it. That is to say, it fixed the time limit (see the provisions of subsections (1), (3) and (4)) and it included the discretion to extend time if the time limit was exceeded (see section 123(1)(b)). I agree with those submissions. Further, Mr Emslie submitted that, in a reasonable adjustments case, one was concerned not with action but with failure to act, that is to say failure to make the reasonable adjustment, or, to put it another way, one was concerned with omission rather than action or conduct. Again, I agree with those submissions. 35. Against that context, one turns to subsection (3) of section 123 to identify the applicable approach to ascertaining the time from which the requirement to present a claim begins to run. Reasonable adjustment cases not being cases of ‘conduct’, but being cases of ‘failure’ to do something, the applicable provision is subsection 123(1)(b). That provides, as set out above, that a failure to do something is to be treated as occurring when the person in question decided on it. That is to say, time runs from when a person, in the present context an employer, decides not to make a reasonable adjustment. Of course, in many cases, there can be no precise identification of when an employer made such a decision. It is for that reason that subsection (4) has been included because it sets a time limit running even in the absence of evidence as to when a person expressly decided to not do something. These are complex provisions as to when time begins to run. Fortunately for this Appeal Tribunal and for the Employment Tribunals on the front line, the provisions of what are now section 123 have been helpfully considered by the Court of Appeal in Matuszowicz v Kingston Upon Hull City Council[2009] EWCA Civ 22 , reported at[2009] IRLR 288 . The Court of Appeal was there concerned with the predecessor provisions of section 123, but the wording is almost identical. In the IRLR, after an explanation of the relevant facts and of the correct approach to section 123, the headnote continues in these terms: “That analysis leads clearly to the conclusions that in the context of the legislation and of the duty to make reasonable adjustments, even if the employer was not deliberately failing to comply with the duty and the omission to comply with it was due to lack of diligence or competence or any other than conscious refusal it is to be treated as having decided upon it at what is in one sense an artificial date. Certainly it may not be a date that is readily apparent either to the employer or to the employee. The date is imposed for the purpose of starting time running under the enforcement provisions.” 36. For his part, Sedley LJ gave a short Judgment, which is summarised in the headnote in this way: “Claimants and their advisors need to be prepared once a potentially discriminatory omission has been brought to the employer’s attention to issue proceedings sooner rather than later unless an express agreement is obtained that no point will be taken on time for as long as it takes to address the alleged omission.” 37. Mr Emslie’s first and most straightforward submission was that the Employment Tribunal had simply failed to direct itself at all in accordance with the statutory provision or the guidance upon it offered by the Court of Appeal. He reminded me that the Tribunal in setting out what they believed to be the relevant law did not set out section 123. Moreover, it is not even mentioned in the relevant part of the written Reasons dealing with the extension of time. There is no reference at all to the decision of the Court of Appeal in the leading case, and nor is there any discussion of the principles which guided the Court of Appeal and which provide so much assistance to Employment Tribunals. Those submissions, in my judgment, beat the air unless it can be demonstrated that the failure to set out the statute and refer to the relevant authority actually made any material difference. 38. One turns again then to the terms of the written Reasons. Mr Emslie submitted that the terms of the written Reasons are themselves revealing. Had the Tribunal had regard to the statute, it would have been concentrating on the employer’s “failure to do something” or alternatively an “omission”
