Despite this, Matheson frequently opposed government policy. In January 1923 he objected to Herbert Greenfield"s government"s continued support of prohibition, remarking "This government has acted as philosopher, guide, and God to the people long enough." In 1926, he expressed frustration with the John Brownlee government"s delay in providing a new police station for his riding, going so far as to threaten to raise the matter in the legislature. In February 1928, he led the opposition to Brownlee"s proposal to exempt lawyers and trust companies wishing to act as real estate agents from the new $1,000 bond required of others wishing to do southern
Matheson proposed eliminating this exemption and raising the amount of the bond to $5,000.
He was partially successful: the bond remained at $1,000 and trust companies remained exempt, but lawyers were barred from the real estate business all together. Matheson was also an active opponent of the Sexual Sterilization Acting of Alberta, and attempted to adjourn debate before it came to a vote.
When he failed, he absented himself from the final vote as a sign of protest. He was a vocal advocate for farmers and in the 1930s proposed unsuccessfully that the government declare a moratorium on the collection of debts from them.
His aggressive approach to the government sometimes paid off, as in his lobbying for the construction of a courthouse in Vegreville.
In 1929 Vegreville was designated as a judicial subdistrict, which entitled it to court offices, a deputy sheriff, and a clerk of court. The following year it was awarded a full courthouse.
