Section 22. Validation

(i) no suit or other proceeding shall be instituted, maintained or continued in any court or other authority against the Government or any person or authority whatsoever for the refund of any amounts paid by a concession holder under clause (b); and (ii) no court shall enforce any decree or order directing the refund of any amounts so paid, on the ground that the mining concession is not a mining lease. (2) For the removal of doubts, it is hereby declared that nothing in sub-section (1) shall be construed as preventing any person,-- (a) from questioning, in accordance with the provisions of the Mines and Minerals Act and the rules made thereunder, the assessment of any dead rent or royalty for the said period; or (b) from claiming refund of any dead rent or royalty paid by him in excess of the amount due from him under the Mines and Minerals Act and the rules made thereunder. 22.
