205. (1) An appeal shall lie to the Federal Court from any judgment, decree or final order of a High Court in British India, if the High Court certifies that the case involves a substantial question of law as to the interpretation of this Act or any Order in Council made there under, and it shall be the duty of every High Court in British India to consider in every case whether or not any such question is involved and of its own motion to give or to withhold a certificate accordingly.
(2) Where such a certificate is given, any party in the case may appeal to the Federal Court on the ground that any such question as aforesaid has been wrongly decided, and on any ground on which that party could have appealed without special leave to His Majesty in Council if no such certificate had been given, and, with the leave of the Federal Court, on any other ground, and no direct appeal shall lie to His Majesty in Council, either with or without special leave.
