Section 6. Determination of claims based on alleged failure of title

Whenever a legal claim is made for a refund of purchase-money because of
  the alleged failure of the title of the state to lands sold  or  granted
  under  its authority including any right, title or interest of the state
  in and to lands under water, the commissioner of  general  services,  if
  satisfied  that  such  claim  is  just  and is made by a person entitled
  thereto, may certify such facts to the court of claims,  whereupon  such
  court  is  empowered  to  determine  the amount of compensation, if any,
  which should be awarded on account thereof,  which  in  no  event  shall
  exceed the amount of the purchase price originally paid for such land.
