1. What should I say to my lawyer so as to force him to submit my reply with all the documents in the court?
You can change your lawyer and engage the services of another lawyer so that you can move on with your reply to be filed before the high court.
2. In case no date is fixed by the court to hear the CWP what should be my next step to get a suitable date from the court?
You have to ask your lawyer to talk to the staff of the court to bring the said file on list at the earliest possible.
3. The matter sometimes comes before the Registrar as well. So can we raise the objection before the Registrar that the government departments are not submitting a reply.
No, you have to confine to your case alone.
4. Is it mandatory that the government departments need to submit the reply first?
It is not so, all the respondents have to file their counter
5. What should I do to remove the stay order and enforce the decision of Town and Country Planner.
It is a stay against the town and country planning and not against you hence you cannot seek that relief of vacating the stay.
