5.Further, the lower appellate court has also found based upon the Commissioner's report and plan that the door fitted in the wall situated to the west of the defendant's property is an old door fitted long back and it is not of new origin. Therefore, the case of the plaintiff that during his absence, the defendant without any authority has put up a new door in the common wall and thereby attempting to interfere with his possession and enjoyment of the common wall and as such the defendant is liable to remove the door fitted to the common all did not find favour with the lower appellate court. Further, to buttress the report and plan of the Advocate Commissioner, the witness examined on the side of DW2 has also deposed that the defendant has fitted the door in the wall about 35 years ago and therefore, from his evidence also it could be seen that the door is not of a new origin and put up a long back. In such view of the matter, the lower appellate court has also disbelieved the evidence of PW2 that the door fitted in the wall is of a new origin. The lower appellate court has rightly found that the trial court has proceeded to accept the case of the plaintiff on the footing that the original owner of the properties situated abutting the wall is one and the same. However, it is not the case of the plaintiff himself that the original owner of the properties abutting the wall is one and the same. It could be seen that the approach of the trial court in accepting the plaintiff's case on a ground not raised by the plaintiff himself is erroneous and unacceptable.
