OKMy client was very pleased with the outcome of the hearing. Thank you for your kind assistance in this matter.
OKI have been thoroughly impressed by Kingsleigh Viollet's hard work, tenacity and advocacy skills. My case had been taken on by him at the 11th hour with very little time to prepare but Kinglseigh was able to drill right down into the strengths and weaknesses of the case and pull together an argument within the short time span. However, most impressive was Kingsleigh's ability to present the case in a manner that set the tone in our favour.
On a more personal level, I am very grateful to Kingsleigh Viollet as the positive case outcome was extremely important and deeply meaningful to me.
