Section 71-0517. Witnesses not excused from testifying

No  person  shall  be  excused from testifying or producing any books,
  papers or other documents in any civil or criminal action or  proceeding
  taken  or  had  under  the  provisions of this chapter listed in section
  71-0501 or under titles 5 through 15 inclusive  and  title  33  of  this

  a  crime, or subject him to a penalty or forfeiture. But no person shall
  be prosecuted, punished or subjected to any penalty or forfeiture for or
  on account of any act, transaction, matter or thing concerning which  he
  shall,  under oath, have testified or produced documentary evidence, and
  no testimony so given or produced shall be received against him upon any
  criminal investigation or proceeding; provided, however, that no  person
  so  testifying  shall  be  exempt from prosecution or punishment for any
  perjury committed by him in his testimony.  Nothing herein contained  is
  intended  to  give,  or shall be construed as in any manner giving, unto
  any corporation, immunity of any kind.
