Thanks for all your hard work on the case over the last year.

I was very impressed by your performance under cross examination and in the hot tubbing session. You got the tone absolutely spot-on in terms of explaining your position with authority whilst recognising your obligations to be a neutral expert.

I wanted to thank you again for all your help and all the time you put in preparing for the hearing. I know cross-examination isn’t fun, but on the whole I thought you went well and you stood your ground.– I have enjoyed working with you and learning just enough about LPG plants to be dangerous
