He served in the Legislative Assembly of Manitoba from 1932 to 1938, representing the Independent Labour Party.
[citation needed] The younger Hyman was educated at Worcester College, Oxford, and received five scholarships during his time in England.
His re-election in the 1936 election was not guaranteed,[2] as the ILP faced strong opposition from the Communist Party and independent leftist Lewis Stubbs.
Hyman was one of the most respected members of the legislature, and spoke on subjects such as education, civil liberties and labour legislation.
He is remembered particularly for having co-sponsored the province's Anti-Defamation Bill, which allowed members of a racial or religious group to sue for an injunction against a defaming publisher or author.
Known as the "Hyman Act", this bill was supported the John Bracken government and given unanimous passage in 1934.
