The city is attempting to have eight protesters found in contempt of court for breaching an injunction prohibiting protests at development sites in the city.
Justice Harrison Arrell said he was concerned that the men could face criminal charges if they were served with warrants and failed to appear in court.
The city's motion asks the court to fine or jail those who are found to have violated the motion and award the city punitive damages.
City lawyer Neal Smitheman said they had successfully served Steve (Boots) Powless and John Garlow. He said Dick Hill refused to accept the court documents, but is aware of the city's motion.
The other protesters named in the action -- Butch Thomas, Clyde Powless, Kevin (Whodat) Isaacs, Dwayne Maracle and Runs Through the Fire -- have not been served.
