1. The plaintiffs in O.S.No.7 of 2007, on the file of the Principal District Judge, Erode, are the revision petitioners.

2. The suit was filed by the revision petitioners for specific performance of an agreement of sale entered into between the plaintiffs and the respondents 1 and 2 on 16.07.2003 and for injunction. During the pendency of the suit, the third respondent was impleaded as third defendant and the suit was dismissed for default on 17.04.2008 and before the restoration of the suit, on 14.07.2008, the respondents 3 and 4 colluded and sold the property to the fourth respondent and therefore, the revision petitioners filed an application to implead the fourth respondent, who is the subsequent purchaser, as one of the defendants in that suit. That petition was dismissed by the Lower Court and aggrieved by the same, this revision is filed.

3.
