The Treason Act 1702 (1 Anne Stat. 2 c. 21) is an Act of the Parliament of England, passed to enforce the line of succession to the English throne (today the British throne), previously established by the Bill of Rights 1689 and the Act of Settlement 1701.
The Act makes it treason to "endeavour to deprive or hinder any person who shall be the next in succession to the crown for the time being ... from succeeding after the decease of her Majesty (whom God long preserve) to the imperial crown of this realm and the dominions and territories thereunto belonging".
Although the Act was passed by the English Parliament, it was later extended to Scotland by the Treason Act 1708, following the Union of the two kingdoms in the previous year. The Parliament of Ireland passed a law to the same effect in 1703, the Treason Act (Ireland) 1703 (c.5). This is still in force in Northern Ireland.
