This article is a fascinating (at least to lawyers who represent survivors of sexual abuse) review of the development of the law in the U.K. regarding time limits for filing civil claims for compensation for sexual abuse.
Until recently, I would have said that Canada, and Nova Scotia in particular, had the most liberal time limits for filing civil claims for historical sexual abuse. Based on this article I believe that the U.K. may now have taken the lead in protecting the rights of survivors of childhood sexual absue.
