Marriage (Same Sex Couples) Bill

Perhaps my noble friend will forgive me if I raise one point with him. Have there not been numerous occasions when this House, even when it was largely hereditary, rejected Bills that had come here from the House of Commons on Second Reading? I have a big memory of the War Crimes Bill that came here from the House of Commons having been passed there by an almighty majority, far greater that the majority given to this Bill in the House of Commons. Nobody in this place suggested that anyone would be behaving improperly if that Bill was rejected by this House. What has changed?
