Eh?

Slander of Women Act 1891 (1891 c 51)
1 Amendment of law
Words spoken and published . . . which impute unchastity or adultery to any woman or girl shall not require special damage to render them actionable.

Provided always, that in any action for words spoken and made actionable by this Act, a plaintiff shall not recover more costs than damages, unless the judge shall certify that there was reasonable ground for bringing the action.

Well there you go. What a strange act to still be in force. I don't quite know what to say.
