milnews.ca said:"Honour of the Crown" is based, in part, on Treaties signed way back -- no such instruments in place dealing with vets, though.
The legal concept of “The honour of the Crown” was the exact legal thrust of the Equitas veterans’ lawsuit against the New Veterans Charter. Federal Court ultimately ruled against them, and the SCC denied leave to appeal. Unless a government we’re to explicitly pass legislation enshrining a comparable obligation on the government (fat chance), it’s dead as a legal concept applicable to veterans. Law around veterans’ benefits has mostly closed the gap with existing civilian workers’ comp systems.
