on the ground that they are not aware of a particular sale transaction that has taken place in the year 1987 in respect of a joint family property. Now, they want to add that property which is sold in the year 1987 as part of the suit schedule property and also implead the purchaser of the said property. It is well settled legal position pertaining to the amendment of the plaint that after commencement of the trial, the amendment of the plaint cannot be allowed unless and until the Court is satisfied that in spite of the due diligence, the said facts could not be pleaded by the plaintiff. In this case, according to the plaintiff, in the affidavit that is filed in support of the I.A., it is submitted that they came to know about the said transaction recently and immediately they have come up with the application. This Court has perused the written statement filed by defendant No.3 wherein they have mentioned about the sale transaction in the written statement that is filed on 06.02.2010.
