Court appearance in sec:138 case

I am an accused in an N.I. Section 138 case. It is a false case foisted on me. Anyway that is beside the poit here.  I am on bail now. But ever since my bail 8 months ago, no hearings have been held so far and I have not yet got an oppotunity to present my side of the case. So far 6 times the date of hearing has been fixed but not a single hearing has been held. The reason is that the magistrate's post is vacant and no new magistrate has been appointed so far. I go to court, Then I am told there is no magistrate and there will be no hearing. I return.

When a date was fixed for a hearing but the hearing was not held on the date and if I knew in advance that the hearing would not be held, is it mandatory on the accused to appear in the court. Generally if a hearing in held and the accused on bail does not appear an arrest warrant could be issued. Can such a warrant be issued against me if I do not go to court?
