On June 10,2000, Kebede, a 16 year old, concluded a contract of loan with Bekele. On June 12, 2003 Kebede brought action for the invalidation of the contract on the basis of incapacity. Bekele argued the action for invalidation is barred by lapse of period of limitation since it is now three years from the making of the contract. He argued Kebede should have brought action for invalidation two years from the day the contract was concluded i. e. until June 11, 2002. Is this argument acceptable? Why or why not? ​
