(1) An initiative to the legislature, if enacted by the legislature, is not subject to gubernatorial veto.
(2) An initiative to the legislature may be rejected either by formal action, by informal inaction prior to the end of the regular session to which the initiative was submitted, or by the passage of an alternative measure to be submitted to the voters along with the initiative at the next ensuing regular general election.
(3) An alternative to an initiative to the legislature need not be passed at the regular session to which the initiative itself was submitted but, to be effective, such an alternative must be passed in time to permit its submission to the voters at the same general election as the one at which the rejected initiative, alone, would be required to be voted upon if an alternative measure had not also been enacted.
