There was a $1,000 deposit. It was refunded upon the submission of the financial returns. Basically, in a way, it was a sort of performance bond for the candidates. It was struck down by the courts on charter grounds on the basis that it allowed wealthy, but frivolous candidates to run and prevented poor, but serious candidates from running. It's difficult to see any significant amount being imposed as a prior condition.
I understand you have experts coming after who may have a view on that.
