Article 4-A - Provisions Relating to Steam Corporations; Regulating Price of Steam.
88 - Defense in Case of Excessive Charges for Steam Heat.

ยง 88. Defense in case of excessive charges for steam heat. If it be
alleged and established in an action brought in any court for the
collection of any charge for steam for heat or power, that a price has
been demanded in excess of that fixed by the commission or by statute in
the municipality wherein the action arose, no recovery shall be had
therein, but the fact that such excessive charges have been made shall
be a complete defense to such action.
