"Mr Tinnion was called to give expert evidence on the law of the State of New York. He is very well qualified to do so, having qualified at the New York Bar and practised with two of the most reputable firms in New York over seven years, as well as having a Master's Degree from Harvard. He is also qualified as a Barrister and Solicitor in England. I found him to be an impressive witness who properly discharged his duty to the tribunal; indeed his evidence on the issue of whether under New York law the employer has a right of suspension without pay, his evidence directly contradicted the Second Respondent's case and led to the Claimant's claim for unpaid wages against the Second Respondent being conceded at a late stage in the proceedings. I accept Mr Tinnion's evidence in its entirety." - Employment Judge Wallington Q.C. Martin v Poseidon Systems Ltd and Poseidon Systems LLC, Employment Tribunals(Scotland) May 2017
