COLORADO: A Colorado judge ruled on Thursday that some people convicted of possessing small amounts of marijuana could have their convictions overturned.

The ruling has to do with the state’s legalization of recreational marijuana in 2012.

Judge Gale T. Miller, writing an opinion for the three-judge panel, found that the constitutional amendment legalizing possession of less than one ounce of pot “applies retroactively to defendants whose convictions under those provisions were subject to appeal or post-conviction motion on the effective date of the amendment.”

In English, that means this is a fairly narrow ruling that affects those who fought charges in court and whose appeals were in process when the amendment went into effect.
