3. Presentation of application.

Notwithstanding anything contained in these rules, the application shall be presented to the Court by the applicant in person, unless he is exempted from appearing in Court, in which case the application may be presented by an authorized agent who can answer all material questions relating to the application, and who may be examined in the same manner as the party represented by him might have been examined had such party attended in person:
Provided that, where there are more plaintiffs than one, it shall be sufficient if the application is presented by one of the plaintiffs.
