This question refers to the summary procedure for the recovery of immovable property provided under the Specific Relief Act, 1963, not the CPC. Section 6 of the Specific Relief Act allows a person who has been dispossessed of immovable property without their consent (otherwise than in due course of law) to file a suit for recovery of possession. Section 6(2) explicitly states that no suit under this section shall be brought "after the expiry of six months from the date of dispossession." This is a quick, summary remedy focused only on restoring possession, and it has a very short limitation period.
