Section 401(e) was not intended to limit the right of a labor
organization to take disciplinary action against members guilty of
misconduct. So long as such action is conducted in accordance with
section 101(a)(5), a union may, for example, if its constitution and
bylaws so provide, bar from office for a period of time any member who
is guilty of specific acts, such as strikebreaking, detrimental to the
union as an institution. However, if a union has improperly disciplined
a member and barred him from candidacy, the Secretary may, in an
appropriate case, treat him as a member in good standing entitled to all
of the rights of members guaranteed by title IV.
