Step 1: Understanding the rule of disqualification.
The law seeks to ensure impartiality and avoid conflict of interest in judicial proceedings. An advocate practicing in a particular court is closely connected with that court’s functioning.
Step 2: Statutory prohibition.
The criminal procedural law expressly bars an advocate from acting as a Magistrate in the same court or within its local jurisdiction where he practices, to maintain judicial neutrality and public confidence.
Step 3: Examination of options.
Options (A), (B), and (C) incorrectly permit such appointment in varying degrees. The law imposes an absolute prohibition without exception.
Step 4: Conclusion.
Therefore, the correct answer is (D) shall not sit as a Magistrate in that Court or in any Court within the local jurisdiction of that Court.
