No, that is always available by just not bothering to tick any box
on the ballot paper etc.

No mark on a ballot paper is just asking for some one to mark it. OK
shouldn't happen but ...

There would have to be a "No Suitable Canditate" option.

SWMBO'd and myself where wondering if one could form a new political
party called "The No Suitable Candidate Party" and run candiates in a
few elections. Trouble is I have a feeling they would also have to be
prepared to take the seat. Unlike nearly all the other small parties
that pop out of the woodwork come election time.
