PHOENIX (AP) — A voter initiative legalizing recreational cannabis will be on the November ballot after the Arizona Supreme Court on Wednesday rejected a final legal challenge to the measure.

A lower court judge had thrown out the challenge, saying the group called Arizonans for Responsible Drug Policy didn’t have a right to sue. Maricopa County Superior Court Judge Jo Lynn Gentry’s ruling went on to reject all of the reasons opponents laid out for keeping the initiative off the ballot.

The opponents said initiative backers used illegal and unconstitutional “bait-and-switch tactics” and that the initiative violates Arizona’s statutes in three ways. They include a misleading 100-word summary that leaves out important provisions, an “incoherent” text and title that obscures the extent of its impact on other laws and a failure to provide a legal funding mechanism.

The high court sidestepped the right to sue argument, with Chief Justice Scott Bales calling Gentry’s reliance on a 2015 rewrite of a law “murky at best, and rather than wade into those waters, we turn to the merits.”

Bales went on affirm Gentry’s ruling rejecting the merits of the opponents’ lawsuit, saying the summary substantially complied with the law’s requirements for initiatives.

The ruling means that Proposition 205 is on November’s general election ballot.

Under the measure, adults age 21 and older could carry up to one ounce of cannabis and consume it privately. Adults could also cultivate up to six marijuana plants in an enclosed space and possess the cannabis produced by the plants. No more than a dozen plants would be allowed in a single residence.

The system would regulate cannabis in a way proponents say is similar to alcohol, with a 15 percent tax on all retail cannabis sales. Most of the new state revenue would go to Arizona public schools and education programs.

Barrett Marson, spokesman for the Campaign to Regulate Marijuana Like Alcohol, said it was “a good day for voters who want to end marijuana prohibition in Arizona.”

“Voters will get the opportunity that they requested — more than 258,000 people signed a petition to put this before the voters,” Marson said. “The Supreme Court agreed voters should have the final say on whether adults should have the right to legally purchase marijuana.”

The opponents, a group called Arizonans for Responsible Drug Policy that includes two prominent county attorneys and the Arizona Chamber of Commerce, said they will now turn to urging voters to reject the measure.

“Our goal now is to make sure that every Arizonan enters the voting booth in November with a full understanding of both the intended and the unintended impacts of the 20 pages of new laws in Prop 205,” Yavapai County Attorney Sheila Polk said in a statement. “We hope all citizens will read the lengthy legalese before voting and will learn how devastating Proposition 205 would be to our state if passed.”

Opponents say backers have not told voters about changes to DUI laws, child custody issues, employment law and many other laws.
