In case involving action to have petitioner civilly committed as a sexually violent predator, writ petition challenging trial court's denial of motion for protective order against district attorney's requests for admission, is granted as requests for admissions may not be propounded in proceedings under Welfare and Institutions Code section 6600 et seq. since their use would eviscerate the Act's requirement that the state prove its case beyond a reasonable doubt and obtain a unanimous verdict before a person may be committed.
