opinion: JAMESON, District Judge:
  This case is before the court upon the petition of Exber, Inc., d/b/a El Cortez Hotel, pursuant to section 10(f) of the National Labor Relations Act, as amended (61 Stat. 136, 73 Stat. 519, 29 U.S.C. Sec. 151 et seq.) to review an order of the National Labor Relations Board issued on September 29, 1966. The Board has cross-petitioned for enforcement of its order.
  The Board found that the company violated Section 8(a) (1) of the National Labor Relations Act by coercively interrogating certain employees, threatening them with reprisals for engaging in union activities, and creating the impression that it was keeping the employees’ union activities under surveillance. The Board also found that the company discharged five employees because of their union adherence in violation of Section 8(a) (3) of the Act.
  Petitioner operates a hotel, restaurant, bar and gaming casino in Las Vegas, Nevada. On June 29, 1964, the American Federation of Casino and Gaming Employees (Union) filed an unfair labor practice charge, alleging that plaintiff unlawfully discharged William Cox on June 22, 1964. On October 19, 1964, the Union filed a first amended charge alleging that Louis Cantalamessa and Robert Jones were unlawfully discharged on June 28, 1964. On April 21, 1965, the Board issued an unfair labor practice complaint.
  On July 7, 1965, the Union filed a second amended charge, alleging that David Conner and David Waggoner were dis-criminatorily discharged on June 28, 1964. On July 28, 1965, the complaint was amended to add the names of Conner and Waggoner as alleged discriminatees.
  The contentions of petitioner may be summarized as follows:
  1. The amendment to the complaint adding Conner and Waggoner as alleged discriminatees was in fact a new and substitute unfair labor practice charge and is barred by the six-month statute of limitations prescribed by section 10(b) of the Act.
  2. The bias and hostility of the trial examiner deprived petitioner of due process of law.
  3. The Board’s findings that petitioner unlawfully terminated the employment of the five employees are not supported by substantial evidence, and in each instance the employee was discharged for good cause.
  4. The Board’s findings that supervisors of petitioner unlawfully interrogated the employees are not supported by any credible evidence.
  Section 10(b) “has been uniformly interpreted to authorize inclusion within the complaint of amended charges —filed after the six months’ limitation period — which ‘relate back’ or ‘define more precisely’ the charges enumerated within the original and timely charge. The ‘relating back’ doctrine for this purpose has been liberally construed to give the Board wide leeway for prosecuting offenses unearthed by its investigatory machinery, set in motion by the original charge. * * * ” National Labor Relations Board v. Gaynor News Co., 2 Cir. 1952, 197 F.2d 719, 721, Radio Officers Union, etc. v. N.L.R.B., affirmed 347 U.S. 17, 74 S.Ct. 323, 98 L.Ed. 455. (See note 30, 347 U.S. 34, 74 S.Ct. 332).
  The “relation back” doctrine was recognized in a situation factually similiar to this case in N.L.R.B. v. Dinion Coil Co., 2 Cir. 1952, 201 F.2d 484, where at the hearing the complaint was amended to include two employees discharged about seven months before the filing of the amendment. After citing cases construing section 10(b) the court said:
  “The holding of these decisions may be summarized thus: (1) A complaint, as distinguished from a charge, need not be filed and served within the six months, and may therefore be amended after the six months. (2) If a charge was filed and served within six months after the violations alleged in the charge, the complaint (or amended complaint), although filed after the six months, may allege violations not alleged in the charge if (a) they are closely related to the violations named in the charge, and (b) occurred within six months before the filing of the charge.”
  We conclude that the amendment to include the two additional employees who were discharged at the same time and under the same conditions as the two employees included in the first amended charge clearly relates to the violation specified in the original charge, is not inconsistent therewith, and clarifies and properly relates back to the original charge.
  With respect to the other specifications of error, the Board’s determination must be accepted if it has “warrant in the record and a reasonable basis in law”. N.L.R.B. v. Hearst Publications, 322 U.S. 111, 64 S.Ct. 851, 88 L.Ed. 1170. The court may disturb the Board’s determination “only in case the Board has acted arbitrarily and without substantial evidence to support its action.” Consolidated Aircraft Corp. v. N.L.R.B., 9 Cir. 1944, 141 F.2d 785, 787. The court may not displace the “Board’s choice between two fairly conflicting views”, even though the court might have made a “different choice had the matter been before it de novo”. National Labor Relations Board v. Walton Mfg. Co., 1962, 369 U.S. 404, 405, 82 S.Ct. 853, 854, 7 L.Ed.2d 829.
  From a review of the whole record we conclude that the Board’s findings are supported by substantial evidence and that the Board’s order is entitled to enforcement.
  The Board’s findings are affirmed. The petition to set aside the Board’s order is denied, and the Board’s petition for enforcement is granted.
  . Section 8(a) provides in pertinent part: “It shall be an unfair labor practice for an employer—
  “(1) to interfere with, restrain, or coerce employees in the exercise of the rights guaranteed in section 7;
  “(3) by discrimination in regard to hire or tenure of employment or any term or condition of employment to encourage or discourage membership in any labor organization;”
  Section 7, relating to “Rights of Employees”, includes the “right to self-organization, to form, join or assist labor organizations * * *.”
  . Section 10(b) provides 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 * * * ”

  . “Charges of unlawful discharges of designated employees were filed, amended and served by August 21, 1950. This was within six months from July 21, 1950, the date of those discharges. A complaint based on these charges was filed on January 17, 1951. The hearing began February 21, 1951. During the hearing, the Board directed that the complaint be amended, over respondent’s objection, to add the names of two employees — Mary Clemens, discharged July 21, 1950, and Tennent, discharged July 28,1950. These two discharges occurred about seven months before the filing of the amendment. * * * ” 201 F.2d at 491.
  . The case upon which petitioner primarily relies, N.L.R.B. v. Vare, 2 Cir. 1953, 206 F.2d 543, is distinguishable. The original charge in that case was against an estate which was operating a business following the death of a sole proprietor. The amended charge was against a partnership which succeeded the estate. The court concluded that the “amended charges” were in fact “new and different charges alleging new and different unfair labor practices against a new and different respondent”. 206 F.2d at 546.

instruction: What follows is an opinion from a United States Court of Appeals.
  Intervenors who participated as parties at the courts of appeals should be counted as either appellants or respondents when it can be determined whose position they supported. For example, if there were two plaintiffs who lost in district court, appealed, and were joined by four intervenors who also asked the court of appeals to reverse the district court, the number of appellants should be coded as six.
  In some cases there is some confusion over who should be listed as the appellant and who as the respondent. This confusion is primarily the result of the presence of multiple docket numbers consolidated into a single appeal that is disposed of by a single opinion. Most frequently, this occurs when there are cross appeals and/or when one litigant sued (or was sued by) multiple litigants that were originally filed in district court as separate actions. The coding rule followed in such cases should be to go strictly by the designation provided in the title of the case. The first person listed in the title as the appellant should be coded as the appellant even if they subsequently appeared in a second docket number as the respondent and regardless of who was characterized as the appellant in the opinion.
  To clarify the coding conventions, consider the following hypothetical case in which the US Justice Department sues a labor union to strike down a racially discriminatory seniority system and the corporation (siding with the position of its union) simultaneously sues the government to get an injunction to block enforcement of the relevant civil rights law. From a district court decision that consolidated the two suits and declared the seniority system illegal but refused to impose financial penalties on the union, the corporation appeals and the government and union file cross appeals from the decision in the suit brought by the government. Assume the case was listed in the Federal Reporter as follows:
  United States of America,
  Plaintiff, Appellant
  v
  International Brotherhood of Widget Workers,AFL-CIO
  Defendant, Appellee.
  International Brotherhood of Widget Workers,AFL-CIO
  Defendants, Cross-appellants
  v
  United States of America.
  Widgets, Inc. & Susan Kuersten Sheehan, President & Chairman
  of the Board
  Plaintiff, Appellants,
  v
  United States of America,
  Defendant, Appellee.
  This case should be coded as follows:Appellant = United States, Respondents = International Brotherhood of Widget Workers Widgets, Inc., Total number of appellants = 1, Number of appellants that fall into the category "the federal government, its agencies, and officials" = 1, Total number of respondents = 3, Number of respondents that fall into the category "private business and its executives" = 2, Number of respondents that fall into the category "groups and associations" = 1.
  Note that if an individual is listed by name, but their appearance in the case is as a government official, then they should be counted as a government rather than as a private person. For example, in the case "Billy Jones & Alfredo Ruiz v Joe Smith" where Smith is a state prisoner who brought a civil rights suit against two of the wardens in the prison (Jones & Ruiz), the following values should be coded: number of appellants that fall into the category "natural persons" =0 and number that fall into the category "state governments, their agencies, and officials" =2. A similar logic should be applied to businesses and associations. Officers of a company or association whose role in the case is as a representative of their company or association should be coded as being a business or association rather than as a natural person. However, employees of a business or a government who are suing their employer should be coded as natural persons. Likewise, employees who are charged with criminal conduct for action that was contrary to the company policies should be considered natural persons.
  If the title of a case listed a corporation by name and then listed the names of two individuals that the opinion indicated were top officers of the same corporation as the appellants, then the number of appellants should be coded as three and all three were coded as a business (with the identical detailed code). Similar logic should be applied when government officials or officers of an association were listed by name.
  Your specific task is to determine the total number of appellants in the case that fall into the category "private business and its executives". If the total number cannot be determined (e.g., if the appellant is listed as "Smith, et. al." and the opinion does not specify who is included in the "et.al."), then answer 99.
