Validation of past excise actions deemed effective; bars suits and enables recovery of duties and refunds. Section 132 retrospectively validates actions, omissions and instruments under rules, notifications or orders made under the Central Excise Act during the specified historical period by deeming them as if the amendment in section 131 of the Finance Act, 2001 had been in force at all material times; it bars suits or enforcement against such validated actions and permits recovery or adjustment of duties, interest, penalties, fines or duty credits as if the amendment had always applied, while clarifying that no new punishable offence is created by this validation.
