The supreme court today filed an appeal before itself challenging the Delhi high court order saying that the office of the Chief Justice of India came under the ambit of the RTI Act.

The petition, which has been filed after CJI K G Balakrishnan had consultation with his fellow judges, raised the point that information held by the CJI is sensitive in nature and its revelation would hamper the judiciary's independence.

The petition, though drafted more than a month ago, was filed on Monday by advocate Devdutt Kamat on behalf of the apex court registry and the case would be argued by the Attorney General G E Vahanvati.

The apex court will be seeking immediate stay on the high court rulings otherwise it would be under obligation to reveal information under RTI Act.

In a path-breaking verdict, the Delhi high court had on January 12 held that the office of the Chief Justice of India comes under the purview of the RTI Act and rejected a supreme court appeal, saying judicial independence is not a judge's personal privilege but a responsibility cast upon him.

The verdict was being seen as a setback to Balakrishnan who has consistently been maintaining that his office does not come under the transparency law and hence cannot part with information like disclosure of judges' assets under it.
