Your Instructing Solicitor Is Your Colleague, Isn't He?
There is a question that every expert working inside a multi-disciplinary practice should expect in cross-examination, and it is not really about methodology. Your instructing solicitor works for the same group as you. You share a brand, a client relationship and, ultimately, a set of accounts. Explain to the tribunal why your opinion is your own. It is a fair question. An expert who cannot answer it crisply, on the first attempt, has a problem that no amount of technical rigour will repair.
