Think I might have just found my new favourite Liberal party politician. That is until the party kicks him out.

He revealed had been told by the premier, Gladys Berejiklian, that he could not have a conscience vote on the matter, which means he faces serious sanctions, including possible expulsion from the Liberal party.

But he said that while he was uncomfortable with the censure, he believed one of the duties of the upper house was to call the executive to account. The denial of access to the documents “interferes with the capacity of the house to fulfil its role,” he said.

In previous debates, Mason-Cox said the government “used to pride ourselves as transparent and accountable government”.

“Lately, this has been replaced by a perverse culture of secrecy, undermining public confidence in government decision-making,” he said.
