The Act does not and unions may not regulate the contents of campaign literature which candidates may wish to have distributed by the union. This is left to the discretion of each candidate. The labor organization may not require that it be permitted to read a copy of the literature before it is sent out, nor may it censor the statements of the candidates in any way, even though the statement may include derogatory remarks about other candidates. Furthermore, a union's contention that mailing of certain campaign literature may constitute libel for which it may be sued has been held not to justify its refusal to distribute the literature, since the union is under a statutory duty to distribute the material. \37\---------------------------------------------------------------------------
