The Colorado Court of Appeals has ruled that residents there convicted of marijuana possession before recreational weed was legalized may be eligible to have those decisions overturned.

As of January 1, 2014, adults from Colorado are legally allowed to buy up to one ounce of marijuana under the state Constitution’s recently passed Amendment 64. But with upwards of 9,000 marijuana possession cases being prosecuted each year before then, a huge chunk of the state’s population is now left wondering how the newly enacted law impacts previously decided court rulings.

Earlier this month on March 13, the three judges of the state’s appeals panel said that part of an earlier decision in a case against a Colorado woman sentenced in 2011 for marijuana possession should be vacated.

In making their decision, the appellate court wrote that there could be post-conviction relief if "there has been significant change in the law."

"Amendment 64, by decriminalizing the personal use or possession of one ounce or less of marijuana, meets the statutory requirement for 'a significant change in the law' and eliminates and thus mitigates the penalties for persons convicted of engaging in such conduct," the judges opined.

A spokesperson for Colorado Attorney General John Suthers has since told NPR that the office will likely appeal the court’s latest ruling, but if it stands then it will set the stage for a substantial number of residents to have their convictions reversed.

This month’s ruling doesn’t affect everyone, though. The appeals court weighed in particularly on the case of Brandi Jessica Russell, a Colorado woman who was sentenced in August 2011, to serve two concurrent four-year terms of supervised probation, 192 hours of community service and a suspended sentence of 90 days in jail after being convicted of possessing a small amount of marijuana, marijuana concentrate and methamphetamine.

Attorneys for Russell filed an appeal shortly after, but it wasn’t heard by the court system until after Amendment 64 went into effect on December 10, 2012. Since then lawmakers have allowed for the first legal, recreational marijuana dispensaries in the United States to operate across Colorado, and the state is expected to reap millions of dollars in taxes from those sales by the end of the year. And because Russell’s case was still up in the air at that point, the appeals court said her conviction should be tossed.

“Defendant contends that Amendment 64 should be applied retroactively and that her convictions for possession of marijuana concentrate and possession of less than one ounce of marijuana should be vacated. We agree,” the court wrote.

Brian Emeson, an attorney for Russell, told the Denver Post that "It's a decision that certainly represents the will of the citizens of this state."

Brian Vicente, a pro-marijuana activist who helped write Amendment 64, told the Associated Press that the ruling was a “huge victory” that could affect hundreds of people who were sentenced to jail terms for petty marijuana offenses in recent years and sought appeal.

Critics of the decision fear that, if not fought, it could open the door for citizens to challenge other convictions unrelated to the drug.

"Well-established retroactivity law in Colorado indicates that statutory changes are prospective only unless the General Assembly or the voters clearly indicted an intent to require such retroactive application," he said in a statement earlier this month.
