MEMORANDUM***


3
The Tax Court did not err in enforcing the stipulated settlement.


4
We reject the Valdezes' contention that by its terms the stipulation was to be binding only if and after an appellate court reviewed the Seykota test cases.  The stipulation clearly contemplated that an appeal might not be taken.  For example, the Valdezes stipulated that they would submit an agreed decision when the Seykota cases became final under I.R.C. § 7481.  A case becomes final under section 7481 when the time for filing a notice of appeal expires.  See I.R.C. § 7481(a)(1).  If the parties to the test cases did not file a notice of appeal, an appellate court could not review those cases.  The stipulation also acknowledged that an appeal might not be taken by describing the parties' obligations "[i]f the decision in Seykota ... is appealed."  (ER 49-50 (emphasis added)).  The word "if" shows that the parties were uncertain whether the Seykota cases would be appealed.


5
By failing to raise them in the Tax Court, the Valdezes have waived their arguments (1) that the Tax Court should have rescinded the stipulation on unilateral mistake grounds, and (2) their attorney's allegedly ineffective assistance was an extraordinary circumstance that warranted reopening their case.  See Melvin v. CIR, 894 F.2d 1072, 1076 (9th Cir.1990).


6
In view of the stipulation, we cannot review the merits of the case.  Parties may not appeal a judgment entered with their consent.  Tapper v. CIR, 766 F.2d 401, 403 (9th Cir.1985).  The stipulated settlement states that the Valdezes consented to have judgment entered against them when the Seykota test cases were final.

AFFIRMED.
