"The Tribunal has considered the case of Connelly but distinguishes it on its facts not least because the concession in this case is essentially one of fact rather than law. The concessions have informed the whole basis of the respondents' and as a result the claimant's position from May 2002 until June 2006. The Tribunal considers it too late both as a matter of law and discretion to allow it to be withdrawn. The Tribunal accepts the assertion of prejudice put forward by Mr Napier and as a consequence would not be prepared to exercise any discretion which it considered it had in favour of the respondent." [29] Mr Napier confirmed to us that the prejudice he relied o was as stated by the Tribunal namely that the claimant would suffer stress by the 're-opening' of the issue and that proceedings would be lengthened. [30] He also drew our attention to the discretion vested in the Tribunal in terms ofrule 10 of Schedule 1 to the Employment Tribunal (Constitution and Rules of Procedure) Regulations 2004 and to the overriding objective to deal with cases justly. The Tribunal was regulating its own proceedings in a manner in which it was entitled to do. Relevant Law [31]Section 3A (1) of the Disability Discrimination Act 1995 provides : "
"For paragraph 2(1) to (3) of Schedule 1, substitute – '(1) The effect of an impairment is a long-term effect if it has lasted for at least 12 months. (2) Where an impairment ceases to have a substantial adverse effect on a person's ability to carry out normal day – to – day activities, it is to be treated as continuing to have that effect if that effect recurs." [34] Thus, in addition to qualifying for the statutory protection under s.1 of the Act on the basis that a person was, at the time of the discrimination complained of, disabled in such a way as satisfied the requirements of paragraph 2 of Schedule 1 of the Act, he may qualify for further protection at a time when, although he does not satisfy those requirements, he is able to satisfy the disability requirements of paragraph 5 of Schedule 2 of the Act. [35] We note that rule 10 of the 2004 Regulations empowers the Chairman (and only the Chairman) to make any order in relation to any matter which appears to him to be appropriate. Rule 27(7) provides that, at a hearing, a Tribunal may exercise any powers which may be exercised by a chairman alone under the rules. The exercise of the power must, of course, be subject to the overriding objective that cases should be decided justly. [36] Turning to the matter of res iudicata, we would simply refer to the well known statement of its meaning contained in the case of Edinburgh and District Water Trustees v Clippens Oil co Ltd 1899 1F 899 where, at p.909, Lord Kinnear said : "
" that the case be remitted to the same Employment Tribunal to determine when after August 1999 ( if not August 1999 itself) it was likely that the substantial adverse effects which parties agree the claimant experienced from August 1999 onwards were likely to last for 12 months or more in total." [11] Following that remit, the Employment Tribunal met, outwith the presence of parties and then issued the following decision : "It was the unanimous decision of the Tribunal that the claimant was a disabled person for the purposes of theDisability Discrimination Act 1995 and that from February 2000 it was likely that the substantial adverse effects experienced by the applicant were likely to last for 12 months or more in total." [12] An attempt at mediation failed and the case was listed for a full hearing. On10 April 2005 there was a Case Management Discussion. Dates for the hearing were then fixed; dates in March 2006 required to be abandoned. The hearing was finally fixed for November 2006. [13] On4 July 2006 , the respondents lodged an application in which they sought leave to amend their Notice of Appearance by adding to it the following terms: "Reference is made to a report by Dr Alan Carson dated5 June 2006 the terms of which are held to be incorporated herein, repeated brevitatis causa and are referred to, and in the light of said medical evidence it is contended by the respondent : (1) that by June 2001 the claimant was no longer disabled within the meaning of theDisability Discrimination Act 1995 . (2) Failing which, that by June 2003 the claimant was no longer disabled within the meaning of said Act of 1995. (3) Failing which that by3 July 2006 the claimant was no longer disabled within the meaning of said Act of 1995." [14] That amendment was allowed in terms of an order pronounced on27 July 2006 . [15] A further Case Management Discussion took place on24 October 2006 . Parties indicated that there were no matters on which directions were sought and that the Chairman did not require to prepare any note. In particular, no order was sought and no submissions were made in respect of the amendment of the respondents' Notice of Appearance that had been allowed. [16] The hearing began on6 November 2006 . At the start of day 4, in response to a comment that had been made by Mr Napier QC, who appeared on behalf of the claimant, Mr Grant Hutchison indicated on behalf of the respondents that he wished to make it clear that the concession previously made by the respondents to the effect that the claimant suffers from a relevant disability and has done so since February 2000, when it became apparent that the substantial adverse effects of her condition were likely to last for 12 months or more, was withdrawn, as should, he said, have been clear from the amendment to the Notice of Appearance which had been allowed. [17] The Chairman raised with Mr Grant Hutchison the question of whether he intended to establish not only had the claimant ceased to be relevantly disabled but that the effect was not likely to recur. He did so under reference to Schedule 1(2) of the 1995 Act. Mr Grant Hutchison said he would take time to consider the matter. It appears that no ruling was made regarding the withdrawal of the concession at that point. [18] At the start of the following day ( day 5), Mr Napier made two motions. The first was for amendment of the claimant's application. He wished to add: "For the avoidance of doubt that as from August 2000 she was also discriminated against, as above particularised on the grounds that she was a person had a past disability contrary toSection 2 of the Disability Discrimination Act 1995 ." [19] The second was that he sought an order so as to prevent the respondents from, whether by cross examination or the leading of evidence, to seek to establish that the claimant was not suffering from the adverse effects required by the 1995 Act between August 1999 and May 2002. [20] The Tribunal, having heard submissions, granted both Mr Napier's motions and pronounced the following order which is now appealed against : "1. The Tribunal allows the claimant to amend her originating application by adding at the end of Section 11 the words "For the avoidance of doubt, that as from August 2000, she was also discriminated against as above particularized on the grounds that she was a person who had a past disability contrary toSection 2 of the Disability Discrimination Act 1995 ."
