Survival of suits against collector.

No suit brought against any Collector by any person deeming himself aggrieved by anything done or purporting to be done under this Act, shall abate by reason of the departure from his district of the Collector against whom such suit shall have been brought; but the suit shall be continued against the successor of such Collector in all respects as though it had been instituted against himself. A suit may be brought against any Collector in his official capacity on account of anything done or purporting to have been done under this Act by his predecessor, subject to the limitation prescribed in the preceding section; provided that no Collector shall be personally liable for any official act of his predecessor.
