Illustrative example
A tenant behind on rent comes home to find the locks changed and the power off. The landlord says the arrears must be settled before anyone is let back in.
The section reaches the landlord, agent, manager, superintendent or janitor who willfully or intentionally fails to furnish a service the lease requires, and separately any of those people who willfully and intentionally interferes with the quiet enjoyment of the leased premises - which is where changing the locks sits. What it produces is an offense: the person is guilty of a violation. It says nothing about what the tenant recovers, so the arrears remain a separate question with their own route.
The locks are restored the same day and the power reconnected, and the parties agree a written payment plan for the arrears with a date each month, neither treating the other's step as cancelling it.
