For example, by suggesting that the Minister of Labour uses parliamentary immunity to take an unfair action against a person, he is implying that if he spoke outside the House of Commons the Minister of Labour would be subject to some kind of civil suit, so he is imputing motives to the Minister of Labour.

Based on that paragraph can we conclude that this sentence is true?
He is implying that if he spoke outside the House of Commons the Minister of Labour would never be subject to some kind of civil suit.
