You're quite correct in referring to the draft procedural guidelines, saying that they are seven years retroactive. That is the piece of work from the Ethics Commissioner.
We are mystified as to where he got that figure. When you think about it, once a member ceases to be a member, he does not come under the jurisdiction of the Standing Orders and therefore of the code. Keep in mind further that the Ethics Commissioner only investigates and reports to the House the decision as whether to impose a sanction...whatever to do. Once a member is no longer a member of the House, the House has no jurisdiction over that person.
So we are baffled as to where that seven-year figure came from.
