"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 The Tribunal considers it too late both as a matter of law and discretion to allow it to be withdrawn.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 : "
