The California Constitution (Article VI, sec. 19) prohibits a judge from drawing pay “while any cause before the judge remains pending and undetermined for 90 days after it has been submitted for decision.” A one-page “barrister’s tips” column by Ben Shatz at page 11 of this month’s Los Angeles Lawyer (in PDF format here) gives some nifty background on how this rule is enforced and how it can affect proceedings, including decisions to vacate submission and the scheduling of oral argument.
