In today's rental market it won't be an issue for landlords to find a new tenant.  Plus if you read the entire article you would gotten to the part where .."one of the key groups protected by the bill is tenants who are stalked or sexually assaulted by their landlords."

I'd say the three types of documentation that can get you out of a lease are all legit.  I don't imagine a doctor writing fake sexual assault reports like they do with companion dog letters.  But even if a doctor is willing to risk their practice of a fake note, isn't the it worth the risk if even one person isn't assaulted?
