"retire early in the interests of the Service and in accordance with the Council's Voluntary Early retirement Scheme."
".....a lump sum retiring allowance and retirement pension calculated on the basis of reckonable service plus compensatory added years up to 10 years....."
"5(1) Subject as hereafter in these regulations provided, an employing authority may.....credit an eligible person with a period of service not exceeding the shortest of the following periods -
"Having said that, I note that you make application for early retirement and I would confirm my conversation, which was on a without prejudice basis, with Mr Finch [the Union representative] as to the matter of two added years."
"As a result of the discussions with my Deputy this morning and since you did not report for duty this afternoon as discussed, and since you have not communicated with the office in relation to voluntary early retirement, I can only conclude that you are not prepared to accept either of the alternatives offered to you namely: (i) to return to duty as a senior engineer at [Cardiff].....
"I refer to my letter dated31st October 1988 which was delivered to you by hand on that date, and to your subsequent telephone call to my Deputy.....
"I confirm that I accept the Voluntary Early Retirement offer as fully set out in the [CPO's] letter dated27 October 1988 ."
"The [employers] by their servant or agent [the CPO] threatened the plaintiff that if he did not sign the endorsement at the foot of the letter of1 November 1988 he would be dismissed. Acting under the said threat the plaintiff signed the said endorsement purporting to accept the voluntary early retirement offer .....The plaintiff's signature was appended thereto under threat of dismissal, duress, avoidable and/or unenforceable."
"8. He raises all sorts of issues in relation to the legality of the actions that the respondents took in awarding him his pension. Those issues have already been ventilated in county court proceedings which were decided against him. [The terms of Pers. 43/1 were then quoted] The applicant, as I have just said, took proceedings in the county court in relation to his entitlement which were heard by Mr Recorder Masterman on1 November 1991 when he made a number of findings of fact. Findings of fact which were made between the parties in previous proceedings between the same parties are binding upon this tribunal in proceedings between those same parties if the findings of fact relate to the issues which that court or tribunal had to decide. The law can be summarised in that respect as it is in Harvey:-
"It is to be noted that in all cases where issue estoppel is raised as a defence in subsequent proceedings, it is essential that the issues in those proceedings are identical with those that were determined in the earlier proceedings and also that the findings of fact in the judgment in those earlier proceedings are clear and precise....It is likewise essential that the findings in the first proceedings are necessary for the decision in that case, and also that the decision itself is intra vires the court or tribunal making it; again, if they are not, there can be no estoppel (see O'Laoire)."
"I am satisfied that [the employee's] failure to get in contact with [the CPO] as he should have done was the last straw that broke the camel's back of the Council's patience, and provoked the letter which purported to terminate the plaintiff's employment. It was only when he realised that he had this time gone too far that the [employee] then persuaded [the CPO] to accept that there had been some kind of misunderstanding and that the [employee] agreed to sign the [indorsement on] the letter..... I then have to consider whether the [employee] signed voluntarily in the sense that he agreed to accept early retirement with just two years enhancement in the absence of what I will call any illegitimate pressure. I have no doubt whatsoever that the [employee] was under no misapprehension as to what he was signing for......I am satisfied the Council acted within its powers in offering the early retirement terms which the [employee] accepted, albeit somewhat grudgingly.....It follows from all this that when the [employee] signed to agree to the early retirement package which was being offered, he knew the terms that were being offered even if he was uncertain of the precise statutory basis, and that the Council was proceeding on the basis of the same terms and that there was, therefore, no common mistake nor were the parties at cross purpose."
"But how far is the case one in which the Industrial Tribunal can be said to have relied on the county court decision? As to that, Mr Sendall for the County Council emphasises that the Industrial Tribunal did hear evidence from [the employee] and does state at several passages, some of which we have cited, that it relies not only on what it derived from the judgment of the learned recorder, but also from the evidence that it heard.
