He wrote on Twitter that registering the impeachment motion against Chief Justice was objectionable and unfortunate, terming it a serious attack on the judicial independence.प्र न्या सुशीला कार्की बिरुद्ध कांग्रेस/माओवादीले महाअभियोग दर्तागर्नु आपत्तिजनक र दुर्भाग्यपूर्ण।न्यायिक स्वतन्त्रतामाथि गंभीर आक्रमण— Kamal Thapa (@KTnepal) April 30, 2017The source said the RPP was unhappy with the ruling parties for keeping the RPP, an important ally in the coalition, in dark over the matter.The meeting called for 11 am at the party's central office would take final decision on whether to pull out of the government, the source said.READ ALSO: Impeachment proposal against CJ Karki on Silwal verdict's eve DPM Nidhi objects to CJ impeachment motion, resigns
