88 - Defense in case of excessive charges for steam heat.

§ 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.
