Today's deployment is an effort to prevent further disruptions of hearings into the legality of President Viktor Yushchenko's dissolution of parliament on April 2.
Police reinforcements and a metal fence now separate supporters of Yushchenko and Prime Minister Viktor Yanukovych in front of the court building.
On April 18, thousands pro-Yushchenko demonstrators temporarily blocked justices from entering the court building.
