   ON PETITION TO TRANSFER

SELBY, Justice.

In this case we are asked to examine the issue of whether a covenant not to advertise contained in an agreement to withdraw from a law partnership violates our Rule of Professional Conduct 5.6. However, because the United States Seventh Cireuit Court has examined the same covenant and determined that it is void and unenforceable under § 1 of the Sherman Act, we conclude that notions of comity direct us to dismiss this action as moot.

In 1988, Thomas Blackburn, Charles Sweeney, and Daniel Pfeifer formed a law partnership in South Bend, Indiana. The trio eventually expanded their practice to include offices in Fort Wayne and Lafayette, Indiana. The office at each locale was governed by a separate partnership agreement; each partnership agreement contained a covenant not to compete with the other offices. Raymond Green joined in the partnerships in Fort Wayne and Lafayette, but not in the South Bend partnership. Blackburn and Green managed the Fort Wayne and Lafayette offices, while Sweeney and Pfeifer ran the South Bend office. Concentrating almost exclusively in plaintiff's personal injury cases, each office attracted a significant amount of its business through extensive advertising on television and in the yellow pages.

In 1992, when a dispute arose between the partners, Sweeney and Pfeifer brought an action in state court against Blackburn and Green seeking dissolution of the partnerships. The Allen Superior Court ordered that the partnerships be dissolved and found that the covenants against competition contained in the partnership agreements were void as violative of Indiana's Rule of Professional Conduct 5.6.

The parties subsequently entered into an agreement to facilitate dissolution of the partnerships. This agreement, the "Agreement to Withdraw from Partnership" (Agreement), provides in relevant part:

Sweeney and Pfeifer shall not directly or indirectly, within the areas described on Exhibit "A" attached hereto, do any advertising, including but not limited to, television, radio, newspapers, billboards, direct mail or yellow pages. In consideration of the agreement contained in paragraph 2 herein, Blackburn and Green shall not directly or indirectly, within the areas described on Exhibit "B" attached hereto, do any advertising, including but not limited to, television, radio, newspapers, billboards, direct mail or yellow pages.

The issue before us stems from this Agreement. In December 1992, Blackburn and Green brought a declaratory judgment action in St. Joseph Superior Court. They asked the court to declare the Agreement void and unenforceable as violative of Rule 5.6. The trial court entered partial summary judgment in favor of Sweeney and Pfeifer, which Blackburn and Green appealed.

On July 25, 1994, the Indiana Court of Appeals reversed the St. Joseph Superior Court's decision to grant summary judgment, finding that the Agreement's covenant not to compete was invalid as a restriction on the right of an attorney to practice law, in violation of Indiana's Professional Conduct Rule 5.6, and because the invalid covenant was not severable from the remainder of the Agreement, the Agreement was unenforceable. Blackburn v. Sweeney (1994), Ind.App., 637 N.E.2d 1340. On April 28, 1995, this Court granted Sweeney and Pfeifer's petition for transfer.

Meanwhile, Blackburn and Green mounted a collateral attack on the Agreement in federal court. Blackburn and Green filed an action in federal court challenging the same clause in the Agreement as violative of § 1 of the Sherman Anti-Trust Act. After reviewing Blackburn and Green's Sherman Act claim, the federal district court for the Northern District of Indiana granted summary judgment in favor of Sweeney and Pfeifer. Blackburn and Green then appealed to the Seventh Cireuit. Shortly thereafter, on May 3, 1995, the Seventh Cireuit Court of Appeals issued its opinion for Blackburn and Green, holding that the Agreement "is illegal and unenforeeable[.]" The Seventh Cireuit concluded that the Agreement was a horizontal agreement to allocate markets among competitors, and therefore, a per se violation of the Sherman Act. Blackburn v. Sweeney, 53 F.3d 825 (7th Cir.1995). Such agreements are unenforceable. United States v. Topco Associates, 405 U.S. 596, 92 S.Ct. 1126, 31 L.Ed.2d 515 (1972); Palmer v. BRG of Georgia, Inc., 498 U.S. 46, 111 S.Ct. 401, 112 L.Ed.2d 349 (1990).

In light of the Seventh Circuit's decision, there is no enforceable agreement to interpret. Under the doctrine of comity, Indiana courts are bound to help enforce the laws of other jurisdictions unless such enforcement would result in a violation of Indiana law or injury to local citizens. See Burke v. Burke (1993), Ind.App., 617 N.E.2d 959, 962. The primary goal behind the doctrine of comity is the promotion of good will between jurisdictions and uniformity of decision. Id. It is to advance this goal that we

give preference to such principle and methods of procedure as shall serve to conciliate the distinct and independent tribunals of the state and the Union, so that they may co-operate as harmonious members of a judicial system, coextensive with the United States, and submitting to paramount authority of the same Constitution, laws, [and] federal obligations.

Reconstruction Finance Corporation v. Zimmerman, 76 F.2d 313, 316 (4th Cir.1935).

Accordingly, the Agreement at issue here is unenforceable by order of the Seventh Circuit and we therefore dismiss. We will reserve, for a more appropriate time, decision on the question of whether other restrictions on advertising, consistent with the Sherman Act, might offend our Rules of Professional Conduct.

SHEPARD, C.J., and DeBRULER, DICKSON, and SULLIVAN, JJ., concur. 
      
      . Indiana's Rule of Professional Conduct 5.6 provides:
      A lawyer shall not participate in offering or making:
      
        (a) a partnership or employment agreement that restricts the rights of a lawyer to practice after termination of the relationship, except an agreement concerning benefits upon retirement; or
      (b) an agreement in which a restriction on the lawyer's right to practice is part of the settlement of a controversy between private parties.
