The Quebec Association of Indians, an "ad hoc" association of native northern Quebecers, won an injunction on 15 November 1973 blocking the construction of the hydroelectric project. They were represented by their lawyer James O'Reilly, who became one of the foremost experts in Indian law. The day after the Malouf judgement was issued, two appeals were launched, one against the merits of the Malouf judgement and one an application to the effect that the Malouf judgement should be suspended pending the hearing. One week later the Court of Appeal of Quebec heard the case. The three judges, Lucien Tremblay, Jean Turgeron, and P.C. Casey, suspended the Malouf judgement until the Court of Appeal was ready to hear the case. In 1974 the Court of Appeal overturned the Malouf judgement. Although the judgement was suspended seven days later and overturned in 1974, the Malouf judgement confirmed Quebec's legal obligation to negotiate a treaty covering the territory, even as construction proceeded.
