Note 80 — Chapter XIV · THE REIGN OF JAMES II.
Reading edition
Fox, Appendix, p. 156. "Provided always, and be it further enacted, that if any peer of this realm, or member of the House of Commons, shall move or propose in either house of parliament the disherison of the rightful and true heir of the Crown, or to alter or change the descent or succession of the Crown in the right line; such offence shall be deemed and adjudged high treason, and every person being indicted and convicted of such treason, shall be proceeded against, and shall suffer and forfeit as in other cases of high treason mentioned in this act."
See what Lord Lonsdale says (p. 8) of this bill, which he, among others, contrived to weaken by provisoes, so that it was given up.
