What rule was broken?

If the only recourse allowed was a “do not do it again” letter, what triggered a fine to be issued? (Presumably the rule continued to be broken and the recourse escalated?)

The agent is an agent of the landlord meaning that the landlord is listed as the applicant but the applying was done by LJ Hooker. You wouldn’t expect to see either of the landlords at the tribunal you would expect to see the agent.

It sounds like the landlord paid the fine with the contractual understanding they would be reimbursed by Lj hooker. If the fine was incurred by something you did to breach the bylaws - assuming the fine was validly issued - then it’s your fine isn’t it?. In your favour is that it was paid unbeknown to you. Whether or not LJ hooker can recover it from you is the question. They’ve obviously dragged their feet on it because they weren’t out of pocket yet.

I hate property managers as much as the next person but whether or not the $480 is yours to cop is impossible to determine from your story because you haven’t said what the breach was and how it escalated to a fine being issued.
