SAN FRANCISCO — Three years ago the Third District Court of Appeal held its nose and ruled that nurses were the only school personnel who could give insulin injections to diabetic kids. "We consider not whether California law should, but whether California law does" impose such a limit, wrote Justice Tani Cantil-Sakauye, before she became California's chief justice.

"I concur because I must, not because I want to," added Justice Arthur Scotland.
