Karmaranas points make some sense if the king fully co-operates.
But I don't think the king will be that co-operative. During Sher Bahadur's government, he gave the list from his pocket for the appointment of even secretaries, join-secretaries, president of election comission or Rastra Bank's governor etc.
You can compare him with the CEO of a company who interferes in the tasks of a branch supervisor.
He is an arrogant person and at the moment, his handing over of the power is just an attempt to diffuse the situation.
Revival of parliament through supreme court can make sense but under this constitution, there is no gate to go to constitution assembly. Even 2/3rd majority of the parliament can not alter the main theories of the constitution " Constitutional Monarchy and multipary democracy, if you are to stick with this constitution.
The present constitution has been several times raped and assaulted by this king. Army is still with him as defeated pack of wolves.
So, the only way is to begin from the trail head for the rest of the journey.
1. King announces that people are the source of the nation.And the sovereignity of the country rests in the people. (He has already said this).
2. Same announcement must ask all parties, civic society, maoists, professionals etc to come together for interaction.
3. Formation of an Interim government with a goal project of the election of constituent assembly.
4. Nepali army and the maoist army should be under UN supervision.
5. Promulgate a new constitution by the elected constituent assembly.
6. Formation of the government as directed by the new constituion.
