A B.C. Supreme Court judge says a longtime raw milk advocate who once tried to circumvent regulations through a “cow share” program can’t try to overturn the provincial ban on unpasteurized milk again after two previous unsuccessful attempts.

Judge William Veenstra says in a ruling posted online Monday that raw milk activist Gordon Watson’s latest attempt to change raw milk regulations can’t succeed because the matters have already been heard and decided by the court more than a decade ago.
