As I understand it, TNP's Constitution does not require candidates to accept their nominations. Therefore Govindia and GBM should be legitimate candidates for their respective offices.
JAL, we do have to look at the election law, and not just the constitution, btw. I can't tell if you did or didn't from your post.
July 1st is Friday of next week. No one has heard from GBM yet, but there's no reason why the others who were mentioned can't be renominated at that time, citing their posted willingness to run. JMHO.
