7 Recommendations

  • Garden Court Chambers
“Ms Haigh is extremely competent, has considerable knowledge of her field of expertise and has considerable skills in both interpreting material presented to her and in producing excellent materials for use in trials.
She is very professional in her approach to all issues that arise and is in my view one of the best experts in this field. I have had no hesitation in recommending her to other counsel.  One of the things that has most impressed me is that she is able to get fully prepared for trials with very little lead time (always a problem as defence funding often comes late) and yet the quality of her work and thoroughness outshines prosecution experts who have had  considerably more time on the case and better funding!”
