(1) A minor on attaining majority may, if a sole plaintiff, apply that a suit instituted in his name by his next friend be dismissed on the ground that it was unreasonable or improper.
(2) Notice of the application shall be served on all the parties concerned; and the Court, upon being satisfied of such unreasonableness or impropriety, may grant the application and order the next friend to pay the costs of all parties in respect of the application and of anything done in the suit, or make such other order as it thinks fit.
