15126       J&J CELCOM v. AT&T WIRELESS SERVICES
                           OPINION

TALLMAN, Circuit Judge:

   On March 26, 2003, plaintiff J&J Celcom along with other
former owners of minority interests in nine general partner-
ships involving cellular telephone businesses filed a diversity
suit in the United States District Court for the Western Dis-
trict of Washington alleging that the defendants, AT&T Wire-
less, Inc. (AWS) and nine of its wholly-owned subsidiaries,
violated Washington State law when AWS sold its controlling
interests in those partnerships to affiliated entities. The plain-
tiffs asserted claims of breach of contract, breach of the cove-
nant of good faith and fair dealing, breach of fiduciary duties,
misrepresentation, tortious interference, and unjust enrich-
ment. The defendants moved for summary judgment, and the
plaintiffs cross-moved for partial summary judgment as to lia-
bility. The district court granted summary judgment in the
defendants’ favor, and denied the plaintiffs’ motion. This
appeal followed.

   In a December 26, 2006, memorandum disposition, we
affirmed the district court’s rulings on all issues save for one.
We certified a state law question, framed as follows, to the
Washington Supreme Court in a separate order:

    Does a controlling partner violate the duty of loyalty
    to the partnership or to dissenting minority partners
    where the controlling partner causes the partnership
    to sell all its assets to an affiliated party at a price
    determined by a third-party appraisal, when the
    appraisal and the parties to the transaction are dis-
    closed and the partnership agreement allows for sale
    of assets upon majority or supermajority vote, but
    the partnership agreement is silent on the subject of
    sale to a related party?

J&J Celcom v. AT&T Wireless Services, Inc., 481 F.3d 1138,
1143 (9th Cir. 2007).
            J&J CELCOM v. AT&T WIRELESS SERVICES           15127
   At the time of the order, “[n]o Washington court ha[d] had
occasion to harmonize state case law concerning the fiduciary
duty of loyalty with the Revised Uniform Partnership Act.”
Id. at 1142 (citing Wash. Rev. Code §§ 25.05.005-.907). We
noted that “[w]hether a trial on the minority owners’ fiduciary
duty of loyalty claim is necessary depends entirely upon the
answer provided by the Supreme Court of Washington to our
certified question.” J&J Celcom, 481 F.3d at 1142.

   [1] On October 25, 2007, the Washington Supreme Court
answered the certified question in the negative, finding that a
controlling partner does not violate the duty of loyalty where
the controlling partner causes the partnership to sell its assets
to an affiliated party. J&J Celcom v. AT&T Wireless Servs,
Inc. ___ P.3d ___, 2007 WL 3105742 (Wash. Oct. 25, 2007).
The partnership agreements at issue are dependent upon
Washington law for the question before us. This answer,
therefore, disposes of the last remaining issue between the
parties in favor of the defendants.

  AFFIRMED.
