DENVER - A Denver judge will hear arguments on whether to block a state health board ruling that narrowed the definition of who can supply medical marijuana.

The hearing was called for by medical marijuana advocates who say the state health board's decision last week was made with little notice of the vote.

Denver District Court Judge Larry Naves will preside over the hearing Tuesday morning.

The board temporarily eliminated its definition of "significant responsibility" for a caregiver because it conflicted with an Appeals Court ruling. That ruling said suppliers must do more than just provide medical marijuana to be considered a caregiver.

The state health board will take a final vote Dec. 16.

Meanwhile, there will be no medical marijuana dispensaries in Trinidad.

The Trinidad city council voted unanimously Monday night to prohibit them. A final vote is scheduled for November 17th.
