(1) The electors of the county, by majority vote of such electors voting on the question at any legally called election, may adopt, amend, revise or repeal a county charter. (2) The charter, or legislation passed by the county pursuant to the charter, shall provide a method whereby the electors of the county, by majority vote of such electors voting on the question at any legally called election, may amend, revise or repeal the charter. (3) The county charter and legislative provisions relating to the amendment, revision or repeal of the charter are deemed to be matters of county concern and shall prevail over any conflicting provisions of ORS 203.710 to 203.770 and other state statutes unless otherwise specifically provided by conflicting state statutes first effective after January 1, 1961. (4)(a) Notwithstanding the charter of the county or any other provision of law, the adoption, amendment, revision or repeal of a county charter shall be decided by simple majority vote. (b) Nothing in this subsection is intended to prevent a county from amending its charter to provide for the adoption by a supermajority or double majority vote or by any other heightened vote requirement of measures imposing or increasing fees, taxes, assessments, fines, penalties, charges or any other revenue-generating mechanisms of any kind.
