Superior Court Judge Peter Busch on Friday extended a restraining order that was issued last week that barred the 11,000 nurses from a planned strike.
He said if the nurses were to go on strike as contract talks got under way, it would be an unfair "pressure tactic" to influence negotiations.
UC officials had urged the judge to prohibit the nurses from walking off the job.
