California Code, Government Code - GOV § 68554

Notwithstanding subdivisions (f) and (g) of Section 1770, the Judicial Council may grant any judge a leave of absence for a period not to exceed one year for the purpose of permitting study which will benefit the administration of justice and the individual's performance of judicial duties, upon a finding that the absence will not work to the detriment of the court.  During a study leave, the judge shall receive no compensation, nor shall the period of absence count as service toward retirement, but the time of leave shall not toll the term of office.
