Spousal privilege
Communications privilege

In particular Sir Wilfred cited, as the sole origin of the privilege, section 3 of the Evidence Amendment Act 1853 which provided that, in civil cases, "no husband shall be compellable to disclose any communication made to him by his wife during the marriage, and no wife shall be compellable to disclose any communication made to her by her husband during the marriage". This provision was based on the Second Report of the Commissioners on Common Law Procedure, who referenced the "inviolability of domestic confidence". It was repeated in section 1 of the Criminal Evidence Act 1898, which extended its applicability to the criminal law.
