[2] Prominent decisions by Judge Werker included a 1981 ruling rejecting a petition by a National Labor Relations Board representative seeking a ruling that Major League Baseball owners had committed an unfair labor practice.
[3] If granted, the petition would have prevented the Major League Baseball Players Association from going on strike.
In intellectual property matters, Werker authored an opinion concerning contractual rights to produce films and television programs based on the character Hopalong Cassidy, and presided over a hearing in which heirs to the estate of Edgar Rice Burroughs, the creator of Tarzan, sought to enjoin release of Tarzan, the Ape Man, the 1981 motion picture based on the character, unless certain revealing footage of Bo Derek was cut.
Werker's ruling upholding the set-asides was affirmed by the United States Court of Appeals for the Second Circuit and the Supreme Court of the United States, although subsequent decisions have undermined the authority of the decision.
In 1983, Werker enjoined the enforcement of a rule proposed by the Reagan administration that would have required birth control clinics to advise parents when their minor children were prescribed contraceptives.
