New Delhi: Congress President Sonia Gandhi and her son Rahul Gandhi have moved the Delhi High Court today objecting to a "different treatment" being accorded to a challenge filed by them in the national herald case.

In an application filed in the High Court, the Gandhis have said that their petition challenging a trial court order in the case had been part heard by Justice S Gaur and has now been placed before another judge Justice P S Teji in violation of the procedures and practice being followed by the court.
