                             TITLE 29--LABOR
 
                  CHAPTER 7--LABOR-MANAGEMENT RELATIONS
 
                 SUBCHAPTER II--NATIONAL LABOR RELATIONS
 
Sec. 160. Prevention of unfair labor practices


(a) Powers of Board generally

    The Board is empowered, as hereinafter provided, to prevent any 
person from engaging in any unfair labor practice (listed in section 158 
of this title) affecting commerce. This power shall not be affected by 
any other means of adjustment or prevention that has been or may be 
established by agreement, law, or otherwise: Provided, That the Board is 
empowered by agreement with any agency of any State or Territory to cede 
to such agency jurisdiction over any cases in any industry (other than 
mining, manufacturing, communications, and transportation except where 
predominantly local in character) even though such cases may involve 
labor disputes affecting commerce, unless the provision of the State or 
Territorial statute applicable to the determination of such cases by 
such agency is inconsistent with the corresponding provision of this 
subchapter or has received a construction inconsistent therewith.

(b) Complaint and notice of hearing; answer; court rules of evidence 
        inapplicable

    Whenever it is charged that any person has engaged in or is engaging 
in any such unfair labor practice, the Board, or any agent or agency 
designated by the Board for such purposes, shall have power to issue and 
cause to be served upon such person a complaint stating the charges in 
that respect, and containing a notice of hearing before the Board or a 
member thereof, or before a designated agent or agency, at a place 
therein fixed, not less than five days after the serving of said 
complaint: Provided, That no complaint shall issue based upon any unfair 
labor practice occurring more than six months prior to the filing of the 
charge with the Board and the service of a copy thereof upon the person 
against whom such charge is made, unless the person aggrieved thereby 
was prevented from filing such charge by reason of service in the armed 
forces, in which event the six-month period shall be computed from the 
day of his discharge. Any such complaint may be amended by the member, 
agent, or agency conducting the hearing or the Board in its discretion 
at any time prior to the issuance of an order based thereon. The person 
so complained of shall have the right to file an answer to the original 
or amended complaint and to appear in person or otherwise and give 
testimony at the place and time fixed in the complaint. In the 
discretion of the member, agent, or agency conducting the hearing or the 
Board, any other person may be allowed to intervene in the said 
proceeding and to present testimony. Any such proceeding shall, so far 
as practicable, be conducted in accordance with the rules of evidence 
applicable in the district courts of the United States under the rules 
of civil procedure for the district courts of the United States, adopted 
by the Supreme Court of the United States pursuant to section 2072 of 
title 28.

(c) Reduction of testimony to writing; findings and orders of Board

    The testimony taken by such member, agent, or agency or the Board 
shall be reduced to writing and filed with the Board. Thereafter, in its 
discretion, the Board upon notice may take further testimony or hear 
argument. If upon the preponderance of the testimony taken the Board 
shall be of the opinion that any person named in the complaint has 
engaged in or is engaging in any such unfair labor practice, then the 
Board shall state its findings of fact and shall issue and cause to be 
served on such person an order requiring such person to cease and desist 
from such unfair labor practice, and to take such affirmative action 
including reinstatement of employees with or without back pay, as will 
effectuate the policies of this subchapter: Provided, That where an 
order directs reinstatement of an employee, back pay may be required of 
the employer or labor organization, as the case may be, responsible for 
the discrimination suffered by him: And provided further, That in 
determining whether a complaint shall issue alleging a violation of 
subsection (a)(1) or (a)(2) of section 158 of this title, and in 
deciding such cases, the same regulations and rules of decision shall 
apply irrespective of whether or not the labor organization affected is 
affiliated with a labor organization national or international in scope. 
Such order may further require such person to make reports from time to 
time showing the extent to which it has complied with the order. If upon 
the preponderance of the testimony taken the Board shall not be of the 
opinion that the person named in the complaint has engaged in or is 
engaging in any such unfair labor practice, then the Board shall state 
its findings of fact and shall issue an order dismissing the said 
complaint. No order of the Board shall require the reinstatement of any 
individual as an employee who has been suspended or discharged, or the 
payment to him of any back pay, if such individual was suspended or 
discharged for cause. In case the evidence is presented before a member 
of the Board, or before an administrative law judge or judges thereof, 
such member, or such judge or judges as the case may be, shall issue and 
cause to be served on the parties to the proceeding a proposed report, 
together with a recommended order, which shall be filed with the Board, 
and if no exceptions are filed within twenty days after service thereof 
upon such parties, or within such further period as the Board may 
authorize, such recommended order shall become the order of the Board 
and become effective as therein prescribed.

(d) Modification of findings or orders prior to filing record in court

    Until the record in a case shall have been filed in a court, as 
hereinafter provided, the Board may at any time upon reasonable notice 
and in such manner as it shall deem proper, modify or set aside, in 
whole or in part, any finding or order made or issued by it.

(e) Petition to court for enforcement of order; proceedings; review of 
        judgment

    The Board shall have power to petition any court of appeals of the 
United States, or if all the courts of appeals to which application may 
be made are in vacation, any district court of the United States, within 
any circuit or district, respectively, wherein the unfair labor practice 
in question occurred or wherein such person resides or transacts 
business, for the enforcement of such order and for appropriate 
temporary relief or restraining order, and shall file in the court the 
record in the proceedings, as provided in section 2112 of title 28. Upon 
the filing of such petition, the court shall cause notice thereof to be 
served upon such person, and thereupon shall have jurisdiction of the 
proceeding and of the question determined therein, and shall have power 
to grant such temporary relief or restraining order as it deems just and 
proper, and to make and enter a decree enforcing, modifying and 
enforcing as so modified, or setting aside in whole or in part the order 
of the Board. No objection that has not been urged before the Board, its 
member, agent, or agency, shall be considered by the court, unless the 
failure or neglect to urge such objection shall be excused because of 
extraordinary circumstances. The findings of the Board with respect to 
questions of fact if supported by substantial evidence on the record 
considered as a whole shall be conclusive. If either party shall apply 
to the court for leave to adduce additional evidence and shall show to 
the satisfaction of the court that such additional evidence is material 
and that there were reasonable grounds for the failure to adduce such 
evidence in the hearing before the Board, its member, agent, or agency, 
the court may order such additional evidence to be taken before the 
Board, its member, agent, or agency, and to be made a part of the 
record. The Board may modify its findings as to the facts, or make new 
findings by reason of additional evidence so taken and filed, and it 
shall file such modified or new findings, which findings with respect to 
questions of fact if supported by substantial evidence on the record 
considered as a whole shall be conclusive, and shall file its 
recommendations, if any, for the modification or setting aside of its 
original order. Upon the filing of the record with it the jurisdiction 
of the court shall be exclusive and its judgment and decree shall be 
final, except that the same shall be subject to review by the 
appropriate United States court of appeals if application was made to 
the district court as hereinabove provided, and by the Supreme Court of 
the United States upon writ of certiorari or certification as provided 
in section 1254 of title 28.

(f) Review of final order of Board on petition to court

    Any person aggrieved by a final order of the Board granting or 
denying in whole or in part the relief sought may obtain a review of 
such order in any United States court of appeals in the circuit wherein 
the unfair labor practice in question was alleged to have been engaged 
in or wherein such person resides or transacts business, or in the 
United States Court of Appeals for the District of Columbia, by filing 
in such a court a written petition praying that the order of the Board 
be modified or set aside. A copy of such petition shall be forthwith 
transmitted by the clerk of the court to the Board, and thereupon the 
aggrieved party shall file in the court the record in the proceeding, 
certified by the Board, as provided in section 2112 of title 28. Upon 
the filing of such petition, the court shall proceed in the same manner 
as in the case of an application by the Board under subsection (e) of 
this section, and shall have the same jurisdiction to grant to the Board 
such temporary relief or restraining order as it deems just and proper, 
and in like manner to make and enter a decree enforcing, modifying, and 
enforcing as so modified, or setting aside in whole or in part the order 
of the Board; the findings of the Board with respect to questions of 
fact if supported by substantial evidence on the record considered as a 
whole shall in like manner be conclusive.

(g) Institution of court proceedings as stay of Board's order

    The commencement of proceedings under subsection (e) or (f) of this 
section shall not, unless specifically ordered by the court, operate as 
a stay of the Board's order.

(h) Jurisdiction of courts unaffected by limitations prescribed in 
        chapter 6 of this title

    When granting appropriate temporary relief or a restraining order, 
or making and entering a decree enforcing, modifying, and enforcing as 
so modified or setting aside in whole or in part an order of the Board, 
as provided in this section, the jurisdiction of courts sitting in 
equity shall not be limited by chapter 6 of this title.

(i) Repealed. Pub. L. 98-620, title IV, Sec. 402(31), Nov. 8, 1984, 98 
        Stat. 3360

(j) Injunctions

    The Board shall have power, upon issuance of a complaint as provided 
in subsection (b) of this section charging that any person has engaged 
in or is engaging in an unfair labor practice, to petition any United 
States district court, within any district wherein the unfair labor 
practice in question is alleged to have occurred or wherein such person 
resides or transacts business, for appropriate temporary relief or 
restraining order. Upon the filing of any such petition the court shall 
cause notice thereof to be served upon such person, and thereupon shall 
have jurisdiction to grant to the Board such temporary relief or 
restraining order as it deems just and proper.

(k) Hearings on jurisdictional strikes

    Whenever it is charged that any person has engaged in an unfair 
labor practice within the meaning of paragraph (4)(D) of section 158(b) 
of this title, the Board is empowered and directed to hear and determine 
the dispute out of which such unfair labor practice shall have arisen, 
unless, within ten days after notice that such charge has been filed, 
the parties to such dispute submit to the Board satisfactory evidence 
that they have adjusted, or agreed upon methods for the voluntary 
adjustment of, the dispute. Upon compliance by the parties to the 
dispute with the decision of the Board or upon such voluntary adjustment 
of the dispute, such charge shall be dismissed.

(l) Boycotts and strikes to force recognition of uncertified labor 
        organizations; injunctions; notice; service of process

    Whenever it is charged that any person has engaged in an unfair 
labor practice within the meaning of paragraph (4)(A), (B), or (C) of 
section 158(b) of this title, or section 158(e) of this title or section 
158(b)(7) of this title, the preliminary investigation of such charge 
shall be made forthwith and given priority over all other cases except 
cases of like character in the office where it is filed or to which it 
is referred. If, after such investigation, the officer or regional 
attorney to whom the matter may be referred has reasonable cause to 
believe such charge is true and that a complaint should issue, he shall, 
on behalf of the Board, petition any United States district court within 
any district where the unfair labor practice in question has occurred, 
is alleged to have occurred, or wherein such person resides or transacts 
business, for appropriate injunctive relief pending the final 
adjudication of the Board with respect to such matter. Upon the filing 
of any such petition the district court shall have jurisdiction to grant 
such injunctive relief or temporary restraining order as it deems just 
and proper, notwithstanding any other provision of law: Provided 
further, That no temporary restraining order shall be issued without 
notice unless a petition alleges that substantial and irreparable injury 
to the charging party will be unavoidable and such temporary restraining 
order shall be effective for no longer than five days and will become 
void at the expiration of such period: Provided further, That such 
officer or regional attorney shall not apply for any restraining order 
under section 158(b)(7) of this title if a charge against the employer 
under section 158(a)(2) of this title has been filed and after the 
preliminary investigation, he has reasonable cause to believe that such 
charge is true and that a complaint should issue. Upon filing of any 
such petition the courts shall cause notice thereof to be served upon 
any person involved in the charge and such person, including the 
charging party, shall be given an opportunity to appear by counsel and 
present any relevant testimony: Provided further, That for the purposes 
of this subsection district courts shall be deemed to have jurisdiction 
of a labor organization (1) in the district in which such organization 
maintains its principal office, or (2) in any district in which its duly 
authorized officers or agents are engaged in promoting or protecting the 
interests of employee members. The service of legal process upon such 
officer or agent shall constitute service upon the labor organization 
and make such organization a party to the suit. In situations where such 
relief is appropriate the procedure specified herein shall apply to 
charges with respect to section 158(b)(4)(D) of this title.

(m) Priority of cases

    Whenever it is charged that any person has engaged in an unfair 
labor practice within the meaning of subsection (a)(3) or (b)(2) of 
section 158 of this title, such charge shall be given priority over all 
other cases except cases of like character in the office where it is 
filed or to which it is referred and cases given priority under 
subsection (l) of this section.

which enacted Title 28, Judiciary and Judicial Procedure.
    In subsec. (c), ``administrative law judge or judges'' and ``such 
judge or judges'' substituted for ``examiner or examiners'' and ``such
