It is the intent of the Legislature to reduce the number of gravely disabled persons for whom conservatorship petitions are filed and who are placed under the extensive powers and authority of a temporary conservator simply to obtain an additional period of treatment without the belief that a conservator is actually needed and without the intention of proceeding to trial on the conservatorship petition. This change will substantially reduce the number of conservatorship petitions filed and temporary conservatorships granted under this part which do not result in either a trial or a conservatorship.
