23. As held by the Supreme Court in C. Natrajan v. Ashim Bai, (2007) 14 SCC 183, the limitation would not commence unless there has been a clear and unequivocal threat to the right claimed by the plaintiff. In the case on hand, the plaint averments would clearly show that there has been a clear and unequivocal threat to the right claimed by the plaintiff. As pointed out earlier, in paragraph No.10 of the plaint, the plaintiff has categorically averred that in November 2002, one Mohan Kumar claiming to be a builder called upon the plaintiff and threatened him to vacate the suit premises as he (Mohan Kumar) proposed to purchase the property to put up several flats. It is also averred in the plaint that the plaintiff lodged a police complaint on 2.12.2002. In paragraph No.12 of the plaint, the plaintiff has averred that following several telephone calls threatening him he filed suit O.S.No.6514 of 2002. Before filing the suit, the plaintiff issued legal notice on 18.11.2002 calling upon the defendant to receive the balance consideration of Rs.13,00,000/- and to execute the sale deed. Stating that the defendant has not come forward to execute the sale deed, in December 2002, plaintiff has filed the suit O.S.No.6514 of 2002 for bare permanent injunction. In the plaint averments in C.S.No.264 of 2007, there is a repeated reference to the threats by the defendant in November/December 2002 and also his refusal to fulfil his obligation. Suit for specific performance should have been filed atleast by 2.12.2005. Even though there was such clear and unequivocal threat to the alleged agreement of sale/undertaking, the plaintiff has not chosen to file the suit for specific performance; but filed the suit for specific performance -C.S.No.264 of 2007 only in the month of November 2006. The suit is clearly barred by limitation. Even though the question of limitation is a mixed question of facts and law, the facts are writ large on the face
