A federal court judge in Canada has dismissed requests for an independent investigation into allegations of insider dealing at the Canada Revenue Agency (CRA). The accusations involved former assistant commissioner Ted Gallivan, who was alleged to have approved a secretive tax arrangement benefiting a wealthy corporate lobbyist with offshore accounts. Separately, the Supreme Court of Canada declined to hear an appeal regarding the questioning of a former Alberta energy minister in a $15 billion coal mining lawsuit. This decision compels the former minister to testify, marking a setback for the Alberta government in the ongoing litigation.
