Denver District Judge Robert Hyatt dismissed a lawsuit over language in the so-called blue book, a state-published guide to ballot measures sent to some 1.9 million households.
Legalization activists wanted the judge to stop the printing because they said lawmakers erred when they cut some arguments in favor of legalization. The deleted sentences included an argument that marijuana is not more harmful than alcohol.
The judge ruled that he couldn't intervene in a legislative process and dismissed the lawsuit. That means the arguments in favor of legalization won't be printed in the book.
"The court made the right decision today," said No on 64 Campaign Director Roger Sherman in a news release. "Legislators on the Legislative Council Committee were thoughtful and deliberate when they reviewed and edited the draft language."
Marijuana legalization supporters disagreed.
"What we're seeing is another step of government deception trying to prevent voters from getting proper education on marijuana reform," said Brian Vicente, Co-Director of the Amendment 64 Campaign to Regulate Marijuana Like Alcohol.
Amendment 64 would allow people 21 or older to have small amounts of marijuana without a medical marijuana card, in effect, regulating it like alcohol.
Wednesday, Gov. John Hickenlooper came out against Amendment 64.
Hickenlooper said in a prepared statement that making marijuana legal would send the wrong message about drug use.
Hickenlooper has previously avoided taking a position on the marijuana proposal.
Colorado is currently one of 17 states that allow marijuana use by people with certain medical conditions.
