    • Johnson v Latchman (UKEAT/0239/19/OO) Harry acted for the successful Claimant, responding to an appeal against a decision to extend the time for a Claimant to bring a claim for disability discrimination. Tucker J found that the ET's findings were open to it, and that, in any event, she would have made the same decision.
    • Godwin Jumbo v Zonal Retail Data Systems (UKEAT/0275/19/LA) Harry acted for the Respondent and responded to an appeal against a decision not to allow the Claimant to amend his claim to add four new causes of action where the Claimant had argued the ET had misapplied both the tests for extension of time and the balance of hardship test for applications to amend.
    • Le Page v East London NHS Foundation Trust (UKEAT0161/19/OO) Harry represented the Respondent who successfully applied for costs following withdrawal of the Claimant's appeal. Eady J accepted the Respondent's submissions and awarded costs having found that the appeal was both unreasonable and misconceived.

    • Black v FCO Services - A ten day trial for constructive unfair dismissal and disability discrimination in which the Harry acted for the Respondent (led by Christopher Stone) and successfully restricted the scope of the Claimant's claim to the month prior to dismissal although the claim related to events that took place several years beforehand.
    • Voronov v University Hospital Southampton NHS Foundation Trust - Harry acted for the Respondent in a four-day hearing dealing with the Claimant's allegation that he had not been hired because of his race, age or sexual orientation. Harry successfully defended the Claim in its entirety.
    • Robertson v British Telecommunications plc - Harry acted for the Respondent in the two-day remedy hearing, dealing with issues of pensions loss and loss of earnings over a period of two years following dismissal, and was successful in obtaining judgment in the sum contended for by the Respondent which was roughly half the sum that the Claimant was seeking.
