Opinion for the Court filed by Circuit Judge EDWARDS.
Concurring opinion filed by Circuit Judge HENDERSON. HARRY T. EDWARDS, Circuit Judge:Petitioner Association of Civilian Technicians, Wichita Air Capitol Chapter (“ACT” or “Union”), the collective bargaining agent for a unit of employees at the Kansas National Guard (“Guard”), seeks review of a negotiability determination of the Federal Labor Relations Authority (“FLRA” or “Authority”). The Union submitted a bargaining proposal to the Guard prescribing the manner in which management representatives should address Union agents during collective bargaining negotiations.
The Guard refused to bargain over the proposal and ACT appealed to the Author*191ity. Purporting to apply this court’s decision in United States Department of the Navy, Naval Aviation Depot, Cherry Point, N.C. v. FLRA, 952 F.2d 1434 (D.C.Cir.1992) (“Cherry Point”), the Authority held that the proposal was not within the employer’s duty to bargain, because it determined a condition of employment of management officials by dictating the terms they must use when addressing Union agents. The Union now petitions for review of the Authority’s decision.
Under Cherry Point, a union proposal that purports to regulate the substantive conditions of employment of management officials or other non-unit persons is not negotiable. The Union’s proposal in this case, however, merely seeks to establish standards governing interactions between Union and management representatives during collective bargaining negotiations and in grievance proceedings. The proposal does not fix conditions of employment of management officials. That managers must comply with these procedures does not render that compliance a substantive condition of employment of those personnel. Management officials often must comply with negotiated rules that benefit unit employees; but such compliance never has been construed to be a “condition of employment” for management under the Federal Service Labor-Management Relations Statute. Furthermore, even if the proposal is viewed as regulating a condition of employment within the meaning of Cherry Point, the only persons whose substantive employment interests are implicated are the members of the bargaining unit. We therefore hold that the Union’s proposal is negotiable and grant the petition for review.
I. Background
Petitioner ACT is the exclusive representative of a unit of employees of the United States Department of Defense, National Guard Bureau, Kansas National Guard. The members of the bargaining unit are designated “dual status technicians,” i.e., civilian employees who must become and remain military members of the Guard unit in which they are employed and maintain the military grade specified for their positions. See 32 U.S.C. § 709 (2000).
During the course of collective bargaining with the Guard, ACT submitted a proposal specifying how Union officials should be addressed during collective bargaining negotiations and in grievance proceedings. The proposal stated:
A. Written communication in connection with any matter covered by Chapter 71 of Title 5, United States Code, by the employer to a bargaining unit employee who is a labor organization representative, will not, in addressing the labor representative, refer to military status or rank; the appropriate address will be “Mr.” or “Mrs.” or “Ms.”
B. Oral communication in connection with any matter covered by Chapter 71 of Title 5, United States Code, by the employer to a bargaining unit employee who is a labor organization representative, who is on official time under 5 U.S.C. § 7131, and who is not wearing a military uniform, will not, in addressing the labor representative, refer to military status or rank; the appropriate address will be “Mr.” or “Mrs.” or “Ms.”
C. Written communication - in connection with a grievance or arbitration under the negotiated grievance procedure; Federal Labor Relations Authority, Federal Mediation and Conciliation Service, or Federal Service Impasses Panel proceeding; adverse action; or other dispute concerning a condition of employment - by the employer to a bargaining unit employee who is a party or *192witness in the matter, will not, in addressing the employee, refer to military status or rank; the appropriate address will be “Mr.” or “Mrs.” or “Ms.”
D. Oral communication - in connection with a grievance or arbitration under the negotiated grievance procedure; Federal Labor Relations Authority, Federal Mediation and Conciliation Service, or Federal Service Impasses Panel proceeding; adverse action; or other dispute concerning a condition of employment - by the employer to a bargaining unit employee who is a party or witness in the matter, who is on official time under 5 U.S.C. § 7131, and who is not wearing a military uniform, will not, in addressing the employee, refer to military status or rank; the appropriate address will be “Mr.” or “Mrs.” or “Ms.”
Ass’n of Civilian Technicians, Wichita Air Capitol Chapter, 57 F.L.R.A. 939, 2002 WL 1769264, at *1-2, (2002), reprinted in Appendix (“App.”) 13-14. ACT asserts that the proposal would ensure that collective bargaining occurs in an atmosphere of equality by prohibiting management negotiators from addressing Union officials by their subordinate military ranks. As clarified by the Union, the proposal prohibits only forms of address referring to military status or rank; the proposal does not prohibit Guard officials from addressing Union representatives by their civilian titles or by them first names. See id. at *2, App. 14.
The Guard refused to negotiate over the proposal, declaring it to be outside its duty to bargain under the Federal Service Labor-Management Relations Statute, which governs labor management relations in the federal public sector. Specifically, the Guard contended that the proposal regulated a condition of employment of management officials and was therefore nonnegotiable. ACT appealed the negotiability of the proposal to the Authority.
The Authority held that the proposal was outside the Guard’s duty to bargain and dismissed the Union’s petition. In reaching this decision, the Authority purported to apply Cherry Point, which holds that union proposals to regulate the conditions of employment of managers are outside an employer’s duty to bargain. 952 F.2d at 1441-43. The Authority concluded that because ACT’s proposal “regulates specific words managers may use in conducting labor-management relations aspects of their work,” it “plainly establishes a job requirement applying only to management officials.” Ass’n of Civilian Technicians, 57 F.L.R.A. 939, 2002 WL 1769264, at *4, App. 17. In the Authority’s view, the proposal therefore “directly determines the conditions of employment of management officials” and falls outside the duty to bargain within the meaning of Cherry Point. Id.
ACT filed a motion for reconsideration before the Authority, arguing that the Authority had misinterpreted this court’s decision in Cherry Point. The Authority denied reconsideration. Ass’n of Civilian Technicians, Wichita Air Capitol Chapter, 58 F.L.R.A. No. 71, 2003 WL 190497 (2003), repainted in App. 25-31. ACT timely filed this petition for review challenging the Authority’s decision on the negotiability of the proposal.
II. Analysis
A. The Appropriate Standard of Review
The Federal Service Labor-Management Relations Statute (“Statute”), 5 U.S.C. §§ 7101-7135 (2000), establishes a collective bargaining regime in the federal public sector. See generally Cherry Point, 952 F.2d at 1438. The Statute grants federal employees the right to organize *193and engage in collective bargaining with respect to conditions of employment. 5 U.S.C. § 7102. Management officials and supervisors are not “employees” under the Statute, however, so they are excluded from any recognized bargaining unit. See 5 U.S.C. § 7112(b)(1). The Statute requires employer agencies to bargain in good faith with the agents of unit employees, 5 U.S.C. § 7114(a)(4), (b), and makes the failure to do so an unfair labor practice, 5 U.S.C. § 7116(a)(5).
The FLRA is authorized under the Statute to determine, inter alia, the negotiability of contested collective bargaining proposals. See 5 U.S.C. § 7105; see also Library of Congress v. FLRA, 699 F.2d 1280, 1284 (D.C.Cir.1988) (noting that Congress has delegated authority to FLRA to construe the Statute and to determine whether a proposal falls within an employer’s duty to bargain). We therefore ordinarily defer to the Authority’s reasonable interpretations of the Statute and its resulting negotiability determinations. See Library of Congress, 699 F.2d at 1285; see also Overseas Educ. Ass’n v. FLRA, 827 F.2d 814, 816 (D.C.Cir.1987).
In this case, no deference is due to the Authority’s negotiability determination, because the FLRA purported to interpret a decision of this court. See Am. Bioscience, Inc. v. Thompson, 269 F.3d 1077, 1085 (D.C.Cir.2001); United States Dep’t of Justice v. FLRA, 266 F.3d 1228, 1230 (D.C.Cir.2001). Where an agency interprets and applies judicial precedent, rather than the statute it is charged with administering, we review its decision de novo. This is because “an agency has no special competence or role in interpreting a judicial decision.” New York v. Shalala, 119 F.3d 175, 180 (2d Cir.1997).
Even if we were to apply a deferential standard of review, however, the Authority’s decision in this case would not survive scrutiny. As we explain below, the Authority’s decision is not a reasonable one, because it is founded on an untenable application of the Statute and a misconstruction of Cherry Point. Therefore, we hold that the Union’s proposal is within the Guard’s statutory obligation to bargain and grant the Union’s petition for review.
B. The Negotiability Ruling
The decision in Cherry Point makes it clear that a union cannot bargain over the conditions of employment of non-unit personnel. See 952 F.2d at 1441-43. In that case, we reviewed a decision of the Authority holding that two union proposals were within the employer’s duty to bargain because they “vitally affected” the conditions of employment of bargaining unit employees. See id. at 1436. We reversed the Authority’s ruling, finding that the proposals “[sought] to establish and regulate the conditions of employment of employees in other bargaining units and supervisory personnel.” Id. at 1441. The proposals therefore exceeded the representation rights of the union and were not within the scope of mandatory bargaining. See id.; see also Am. Fed’n of Gov’t Employees, Local 32 v. FLRA, 110 F.3d 810, 815 (D.C.Cir.1997) (‘AFGE”) (explaining that under Cherry Point, a proposal is nonnegotiable if it “would govern the working conditions of supervisors and employees in other bargaining units”).
Because “a union is the exclusive representative of employees in the certified or recognized unit, and those employees only,” an employer has no obligation to bargain with a union over the conditions of employment of employees in another bargaining unit. Cherry Point, 952 F.2d at 1442. Similarly, because the Statute excludes supervisors and management officials from any authorized bargaining unit, “the same policies that prevent a union *194from purporting to regulate the conditions of employment of persons in other units apply with equal force to supervisory personnel.” Id. (citing 5 U.S.C. § 7112(b)(1)). Conversely, under Cherry Point, a union may negotiate the conditions of employment of its own bargaining unit employees, even if those conditions affect personnel outside of that bargaining unit. See AFGE, 110 F.3d at 815; Cherry Point, 952 F.2d at 1440-41.
The Authority’s decision in this case rests primarily on its determination that ACT’s proposal “directly determines” the conditions of employment of supervisory personnel by dictating the forms of address they may use during negotiations and is therefore outside the duty to bargain under Cherry Point. Ass’n of Civilian Technicians, 57 F.L.R.A. 939, 2002 WL 1769264, at *4-5, App. 17-18. This analysis fundamentally misapplies the Statute and misconstrues our decision in Cherry Point. ACT’s proposal in this case relates to the terms of the interactions between union and management representatives during collective bargaining negotiations and in grievance proceedings. The clear purpose of the proposal is to ensure that employees who act as agents for members of the bargaining unit are treated as equals while serving in their representative capacities at the bargaining table or in grievance proceedings. The proposal thus does not come within the proscription of Cheri’y Point. The Union here is not seeking to regulate the substantive conditions of employment of non-unit persons; rather, it is proposing to reach agreement on how the parties’ representatives deal with one another during bargaining and grievance processing.
The FLRA has long recognized that parties in a collective bargaining relationship may propose “ground rules” for negotiations or grievance processing and that such proposals fall within the statutory duty to bargain in good faith. See, e.g., 375th Combat Support Group, Scott Air Force Base, Ill., 46 F.L.R.A. 640, 665, 1992 WL 357703 (1992); Dep’t of Def. Dependents Sch., 14 F.L.R.A. 191, 193, 1984 WL 35618 (1984). A proposed ground rule generally may encompass any “guide for the conduct of ... negotiations.” Am. Fed’n of Gov’t Employees, 16 F.L.R.A. 602, 613, 1984 WL 35247 (1984), remanded on other grounds, 784 F.2d 1131 (D.C.Cir.1986), and aff'd, 21 F.L.R.A. 786, 1986 WL 54754 (1986). And the FLRA assesses the propriety of such proposals by asking whether they are offered in good faith and whether they are designed to further the bargaining process. See United States Dep’t of the Air Force Headquarters, Air Force Logistics Command, Wright-Patterson Air Force Base, Ohio, 36 F.L.R.A. 524, 533, 1990 WL 151132 (1990).
ACT’s proposal prescribes how Union representatives should be addressed solely in the context of collective bargaining negotiations and in grievance proceedings. As such, it is akin to any ordinary ground rules proposal or routine regulation of negotiation procedures. Neither the Guard nor the Authority has asserted that the Union offered this proposal in bad faith. Nor can it be said that the proposal would hinder the bargaining process. To the contrary, by prohibiting references to Union representatives’ subordinate military ranks, the proposal contributes to the equality of the parties’ representatives in collective bargaining and is therefore consistent with a primary goal of the Statute. See, e.g., Am. Fed’n of Gov’t Employees v. FLRA, 750 F.2d 143, 148 (D.C.Cir.1984) (noting the statutory “goal of equalizing the positions of labor and management at the bargaining table”). Accordingly, the proposal clearly falls within the Guard’s duty to bargain.
*195Finally, even if ACT’s proposal is viewed as establishing a substantive condition of employment, the proposal clearly relates to a condition of employment of bargaining unit employees, not their managers. As such, it remains negotiable under the literal terms of Cherry Point. Properly understood, Cherry Point prohibits union proposals that directly implicate the interests of management officials by regulating the terms of the employment relationship between managers or supervisors and their employer. A union that advances such proposals is inappropriately attempting to bargain on behalf of individuals it does not represent. Cherry Point does not, however, prohibit proposals that regulate the conditions of employment of bargaining unit employees merely because those proposals have “some effect” on managers or supervisors. AFGE, 110 F.3d at 815.
The proposal here seeks to ensure that the employees’ bargaining agents retain the full appearance of equal status at the bargaining table and in grievance proceedings. Plain and simple, this is a beneficial condition of employment for bargaining unit employees who serve as representatives in collective bargaining negotiations or in grievance proceedings. Of course, if the parties adopt the Union’s proposal, management officials will be obliged to comply with the terms of the parties’ agreement. But this is true of any union proposal that beneficially changes the conditions of employment of bargaining unit personnel. The fact that management personnel are obligated to conform their behavior during negotiations to these procedural requirements does not establish a substantive condition of employment for those personnel. Such compliance has never been thought to be a “condition of employment” for management under the Statute. We therefore hold that the Authority erred in holding that the proposal was not negotiable.
III. Conclusion
For the reasons noted above, ACT’s petition for review is granted. The Guard is obligated under the Statute to bargain in good faith with the Union over the proposal specifying how Union officials should be addressed during collective bargaining negotiations and in grievance proceedings.
So ordered.
