Gujarat High Court Civil Manual (subordinate court practice), 1960
When an Assistant Judge, a Judge of the Court of Small Causes or a Civil Judge wants to take casual leave, he should apply to his District Judge and get it sanctioned by him before he proceeds on such leave, unless for reasons beyond his control he cannot do so. In the latter case, he should obtain such sanction as soon thereafter as may be possible. If, however, he has to leave his headquarters during his casual leave, he must obtain the previous permission of his District Judge for doing so. But if for any unforeseen reasons or for reasons beyond his control, he is required all of a sudden to leave his headquarters during the period of his casual leave, he should immediately inform his District Judge and mention the reasons which necessitated his leaving headquarters without prior permission.
