The point here is that when it comes time to audit a candidate's return and you are a candidate, you know that you have to provide pieces of substantiating claims, vouchers, for your expenditures to vouch for what you have spent.
I get no such documents from parties. From parties I only get headings and numbers. I have no idea. There is no way to do any kind of review. This section would require that this be provided, and where it was not provided I could seek it out. But there would be protection for individuals, because only through a court order would that be permissible when it touched an individual. But if it touched a bank, for example, then the authority would be granted to the Chief Electoral Officer before prosecution, before an investigation, to look at the books.
