In 1984, an agreement was signed, revising the concordat. Among other things, both sides declared: "The principle of the Catholic religion as the sole religion of the Italian State, originally referred to by the Lateran Pacts, shall be considered to be no longer in force". The Church's position as the sole state-supported religion of Italy was also ended, replacing the state financing with a personal income tax called the "otto per mille", to which other religious groups, Christian and non-Christian, also have access. , there are ten other religious groups with access. The revised concordat regulated the conditions under which civil effects are accorded by Italy to church marriages and to ecclesiastical declarations of nullity of marriages. Abolished articles included those concerning state recognition of knighthoods and titles of nobility conferred by the Holy See, the undertaking by the Holy See to confer ecclesiastical honours on those authorized to perform religious functions at the request of the State or the Royal Household, and the obligation of the Holy See to enable the Italian government to present political objections to the proposed appointment of diocesan bishops.
