ISLAMABAD - Islamabad High Court Monday dismissed an intra court appeal seeking a contempt of court proceeding against former prime minister Nawaz Sharif and declared the petition as non maintainable. A divisional bench comprising Justice Athar Minallah and Justice Mian Gul Hassan Aurengzaib took up the appeal against former prime minister filed by a citizen Makhdoom Niaz Inqalabi. The petitioner had stated in his plea that Nawaz Sharif had criticised the judges of apex court during his march from Islamabad to Lahore after his disqualification. It came under the contempt of court, he claimed. After hearing the arguments, the court dismissed the case and declared it non-maintainable.
