A Maricopa County Superior Court judge has thrown out a legal challenge to an initiative that would ask voters in November to legalize marijuana. Opponents of the measure are expected to appeal the decision.

The judge ruled that opponents of Proposition 205 cannot challenge the initiative because of changes to the law that would limit such lawsuits. She said the state legislature eliminated a part of the law that would allow a citizen to challenge the legality of initiative petitions.

Opponents had asked that the measure be kept off the ballot because the short description voters saw when signing petitions left off many major provisions.

For instance, the 100-word legal description did not include details about changes to DUI laws, child custody issues or employment law.

The Secretary of State has certified the measure for the upcoming general election.
