The U.S. Supreme Court case Building Service Employees International Union, Local 262, et al. v. Gazzam in 1949 revolved around the issue of whether a state could constitutionally enforce a statute that required labor unions to provide equal representation for all employees within their bargaining unit, regardless of union membership status. The appellant was an international union and its local affiliate who were charged with violating Washington State's law by refusing to represent non-union members during collective bargaining negotiations with employers. They argued that this requirement violated their First Amendment rights as it forced them into association with individuals they did not wish to associate with. However, the court ruled against the appellants upholding the validity of Washington’s law requiring labor unions representing workers in industries affecting public interest (like transportation or communication) to equally represent both members and non-members alike in collective bargaining processes without discrimination on account of union affiliation or lack thereof.

In the dissenting opinion for the case of Building Service Employees International Union, Local 262, et al. v. Gazzam, Justice Robert H. Jackson disagreed with the majority's decision to uphold a Washington state law that required unions to file financial reports and lists of officers as a condition for maintaining picket lines at businesses involved in labor disputes. He argued that such requirements were an unconstitutional infringement on freedom of speech and assembly rights protected by the First Amendment because they imposed burdensome conditions on union activity without serving any compelling public interest or achieving any significant regulatory objective. Furthermore, he contended that these reporting obligations could potentially be used as tools of harassment or intimidation against union leaders and members by employers seeking to resist their organizing efforts or undermine their bargaining power.
