In an action brought by parent's challenging the detention of their children for six months, specifically, the two months they were detained in Orange County before the case was transferred to Los Angeles, the trial court's grant of summary judgment to social worker-defendants is affirmed where: 1) the parents' knowing and voluntary pleas of no contest to the jurisdictional allegations during dependency proceedings defeats their claims; 2) the social workers are entitled to immunity; and 3) met their burden to establish they were entitled to summary judgment on each cause of action, and plaintiffs failed to raise triable issues of material fact.
