Section 24. Costs and fees

If the court before which any proceedings for
  compensation or concerning an award of compensation have  been  brought,
  under  this  chapter,  determine  that such proceedings have not been so
  brought upon  reasonable  ground,  it  shall  assess  the  cost  of  the
  proceedings  upon the party who has so brought them. Claims of attorneys
  and counselors-at-law for legal services in connection  with  any  claim
  arising  under  this  chapter,  and  claims  for  services  or treatment
  rendered or supplies furnished pursuant to subdivision  (b)  of  section
  thirteen  of  this  chapter, shall not be enforceable unless approved by
  the board. If so approved, such claim or claims shall become a lien upon
  the compensation awarded, and upon any  moneys  ordered  paid  under  an
  award  by  the  board  into  the  special  funds provided for in section
  fifteen, subdivision nine, and  section  twenty-five-a,  and  any  other
  section  of this chapter, but shall be paid therefrom only in the manner
  fixed by the board. Any other person,  firm  or  corporation  who  shall
  exact  or receive fee or gratuity for any services rendered on behalf of
  a claimant except in an amount determined by the board, shall be  guilty
  of  a misdemeanor. Any person, firm or corporation who shall solicit the
  business of appearing before the board on behalf of a claimant,  or  who
  shall  make  it  a  business  to  solicit  employment  for  a  lawyer in
  connection with any claim for compensation under this chapter  shall  be
  guilty  of a misdemeanor. In case an award is affirmed upon an appeal to
  the appellate division, the same shall be payable with interest  thereon
  from  the  date when said award was made by the board except as provided
  in section twenty-seven of this chapter.
