Groups planning protests had sought the information as part of a lawsuit challenging a designated public demonstration zone and route for marches during the convention Aug. 25-28. They say the zone and route will not be within earshot or view of delegates attending events at the Pepsi Center and Invesco Field at Mile High.
The groups argued that knowing staffing plans would help answer whether more officers would be needed if protest or parade areas were moved.
U.S. Magistrate Judge Kathleen Tafoya said Tuesday that some requests were not relevant to the lawsuit and said there were safety concerns. Denver had argued that releasing officers' staffing plans could allow someone to plan to overwhelm forces.
Arguments on the lawsuit are set to be heard July 29.
Separately Tuesday, anti-abortion groups asked City Attorney David Fine whether they could conduct a prayer vigil at the Pepsi Center on Aug. 23. They threatened to file a lawsuit if Denver does not respond.
Fine said public sidewalks would be open Saturday for a vigil and that he was continuing to talk with the groups.
