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.
When coding the detailed nature of participants, use your personal knowledge about the participants, if you are completely confident of the accuracy of your knowledge, even if the specific information is not in the opinion. For example, if "IBM" is listed as the appellant it could be classified as "clearly national or international in scope" even if the opinion did not indicate the scope of the business. 

Your task concerns the first listed appellant. The nature of this litigant falls into the category "federal government (including DC)", specifically "other agency, beginning with "O" thru "R"". Your task is to determine which specific federal government agency best describes this litigant.

Before LUMBARD, Senior Circuit Judge, United States Court of Appeals for the Second Circuit, EDWARDS and BORK, Circuit Judges.
Sitting by designation pursuant to 28 U.S.C. § 294(d) (Supp. V 1981).
Opinion for the Court PER CURIAM.
PER CURIAM:
This appeal involves an arbitrator’s decision in an “adverse action” case arising under the Civil Service Reform Act of 1978. The case is before the court for a second time, and we are again required to review an arbitral judgment — issued pursuant to a contractually established grievance procedure — setting aside a disciplinary sanction imposed by the Immigration and Naturalization Service (“INS”) on one of its agents. The relevant background facts were set forth fully in our first opinion and need not be repeated here.
That first opinion left to the arbitrator the task of determining whether the procedural error he had previously identified was “harmful” within the meaning of 5 U.S.C. § 7701(c)(2)(A) (Supp. V 1981). The INS’s error could be so characterized, we stated, if it either “affected the outcome of the disciplinary proceeding,” or vitiated a substantial right accorded the affected employee by a “clear provision of [the] collective bargaining agreement.” 697 F.2d at 443-44.
On remand, the arbitrator reconsidered and reaffirmed his initial decision setting aside the disciplinary sanction imposed by the INS. Although the arbitrator’s judgment appears not inconsistent with our first decision in this case, it is difficult to fathom any coherent line of reasoning in his long and rambling opinion, which consists almost entirely of random quotes from other sources. In reading his opinion, we are hard-pressed to identify either a glimmer of reasoned consideration, to which we might defer, or a hint that his observations bear any significant relation to the real world.
If government agencies and unions in the federal sector are to bind themselves through collective bargaining agreements to arbitrate disciplinary matters, one would hope that the arbitrators selected — who are given broad authority to construe and enforce labor contracts — have the time, talent and experience to write intelligible opinions. An opinion such as that submitted here forces the court to choose between placing its stamp of approval on utter gibberish or conducting what would amount to de novo review on a hopelessly inadequate record. Both options, of course, are undesirable.
Notwithstanding our dismay over the quality of the arbitral opinion in this case, consistency of the result reached in the arbitrator’s decision with the test established in our original opinion leads us to conclude that approving that result is the lesser of two evils. We therefore affirm the judgment, but not the rationale or opinion, of the arbitrator.
So ordered.
