To reiterate, the three main points are, first, that MSPs may not submit petitions; secondly, that the same people may not resubmit petitions on the same subject after a short interval; and thirdly, that the Public Petitions Committee will decide on the admissibility of petitions if there is a dispute, and any committee may close a petition.In each case, standing orders will say that the committee must tell the petitioner what it has decided to do.
