Hall acted as the defence counsel in the 1928 "Maloney v. Dealtry" libel trial. The plaintiff John James Maloney was a prominent member of the Ku Klux Klan who came to Saskatchewan to promote the Klan in preparation for the upcoming 1929 Saskatchewan general election which had shown signs of religious tension being a decisive factor, with the Klan raising anti-immigrant and anti-Catholic fervour. The plaintiff accused the defendant of seditious libel for comments made in a publication he printed and which, Hall argued as counsel, were seditious because they had caused a public fracas. Hall lost the case and the defendant was fined $200 and prohibited from publishing such material in the future. The Ku Klux Klan burnt an effigy of Hall in response to his participation in the case.
