He was admitted as a solicitor only in 1929, completed an LLM degree (in 1930), and in 1931 was admitted as a barrister.

He prosecuted Walter James Bolton, who was executed in 1957, the last person executed in New Zealand.

Sir Thaddeus was President of the Court of Appeal from 1973 to 1976, and was the presiding member of an unprecedented seven Royal Commissions. He was also a Commissioner of Security Appeals.
