1)  What happens if CA can not complete writing constitution by 2 years and consitutionally allowed 6 months extension? Will country face consitutionally void situation if Consitution is not written by given time framework?  or do these parties can extend time having consensus among them?

1. The 601 member CA is sovereign and has the authority to extend the term for the drafting of the constitution as it pleases them.

 2) If Maoist decide to abstain CA for long time and go for another Aandolan,CA will not have 2/3 majority and deadlock will be created.In that situation,does CA have any right of consitutional ammendment?

2. Unless the CA members themselves change the terms (ie; require only a simple majority instead of a supermajority), there is no easy way to approve a new constitution without a full 2/3 majority.  If any group of CA members abstain to not allow the required 2/3, then the process is stalled.
