When any local area is under settlement and the Settlement-officers therein have been invested with powers under section thirtythree, the Chief Commissioner may withdraw from the jurisdiction of the ordinary Civil Courts within such area the classes of suits which Settlement-officers have power to dispose of under that section, or he may direct that, in respect of such suits, the Settlement-officers shall have concurrent jurisdiction with the ordinary Civil Courts:
     Provided that no proceedings which have been inadvertently or erroneously taken before the Civil Court shall be deemed to be invalid merely on the ground that, by the Chief Commissioner's order, they should have been taken before a Settlement-officer.
