In 1927, Grand Chief Sylliboy was charged by Nova Scotia with hunting muskrat pelts out of season. He was the first to use the rights defined in the Treaty of 1752 in his court defence. He lost his case. In 1985, the Supreme Court of Canada finally recognized the 1752 treaty rights for indigenous hunting and fishing in their ruling on "R. v. Simon". On the 50th anniversary of Sylliboy's death, the Grand Council asked the Nova Scotia government for a pardon for the late Grand Chief. Premier Stephen McNeil granted the posthumous pardon in 2017. Lieutenant-Governor of Nova Scotia, John James Grant, McNeil, and the Justice Minister Diana Whalen, pardoned Sylliboy and issued a formal apology: it was the "second posthumous pardon in Nova Scotia's history". His grandson, Andrew Denny, now the Grand Keptin of the Council, said that his grandfather had "commanded respect. Young people who were about to get married would go and ask for his blessing. At the Chapel Island Mission boats would stop if he was crossing."
