Filing a writ petition would be the last solution. 

Before that you have to exhaust the remedies available before the same SDM court.  If an order under section 144 cr.p.c has been passed,  you may file a petition before same court to vacate the orders for the reasons you may rely upon. 

If your petition is dismissed,  you may prefer an appeal against the aggrieved dismissal before appellate tribunal. 

If you don't get justice in the appeal also then you can approach high court with a writ petition seeking relief. 

If the other person also has filed a suit seeking some other relief against you,  it may be challenged as per law in the same court. 

Thus without exhausting the remedies available before you,  your writ petition before high court would not be entertained. 

Yes you can make police authority a party and file writ

you file an appeal against the order passed by the sdo before collector.
