Section 235-B*2. Effect of usury

The  knowingly  taking,  receiving,
  reserving, or charging by a savings bank of interest at a  rate  greater
  than such rate of interest as may be authorized by law shall be held and
  adjudged  a  forfeiture  of  the entire interest which the note or other
  evidence of debt carries with it, or which has been agreed  to  be  paid
  thereon.  If  such  greater  rate  of interest has been paid, the person
  paying the same or  his  legal  representatives  may  recover  from  the
  savings  bank  twice  the  entire  amount  of the interest thus paid, if
  action therefor is brought within two years from the time the excess  of
  interest is taken. Nothing in this section shall be deemed to affect the
  powers  of  any  savings bank with respect to loans or investments it is
  authorized to make.
