The PC boundary and district boundary need not match, it may in some cases. In most cases PC may overlap districts. So I don't think you can fix it by any conditioning. Yes u can combine the PC and create state boundaries.

awesome work with the conversion, we finally have some good boundary data to work on. i compared the data with the state maps and the pc boundaries dont seem consistent with the districts as i had initially thought, so it might need some conditioning before upload. since each state is available as a seperate file, by combining the sonstituencies, we can get the state border. using josm, i did the combining and i am uploading the tamil nadu border.
we will certainly need some discussion on how to tag this data.
shajeer, the eci data is under a mit style license http://eci.nic.in/DevForum/DevForum.asp so i guess its all good.

These file have details about on assembly constituency/parliament name.
There is no district boundaries or other administrative boundaries
available. So does it make sense to have them in OSM?
Also before loading to OSM, there are couple of things that we need to take
care
1. of course the license itself
2. What attributes from the shapefile we should take? (state name, assembly
constituency/parliament name, local name, etc..).
I have found files this source to have district boundaries and state
boundaries. No idea abt the license
