or any other person interested, to apply to the court for leave to continue the suit. But it does not follow that it is obligatory upon them to do so. If a party does not ask for leave, he takes the obvious risk that the suit may not be properly conducted by the plaintiff on record, and yet, as pointed out by Their Lordships of the Judicial Committee in Moti Lal v. Karrabuldin [ILR (1898) 25 Cal 179 : 24 IA 170 : 1 CWN 639 (PC)] he will be bound by the result of the litigation even though he is not represented at the hearing unless it is shown that the litigation was not properly conducted by the original party or he colluded with the adversary. It is also plain that if the person who has acquired an interest by devolution, obtains leave to carry on the suit, the suit in his hands is not a new suit, for, as Lord Kingsdown of the Judicial Committee said in Prannath Roy Chowdry v. Rookea Begum [(1857-60) 7 MIA 323], a cause of action is not prolonged by mere transfer of the title. It is the old suit carried on at his instance and he is bound by all proceedings up to the stage when he obtains leave to carry on the proceedings.’
