Can you file petition with police for demolishing house which is decreed by lower court and is pending in High court third party purchased and constructing inspite of giving telegram not to construct?

You need to review the situation with an attorney. Since there is an appeal pending regarding the land, there should have been a notice recorded in the land records that would have alerted any third-party purchaser. Depending on the decision of the High court, you may have to sue someone for damages.
