OVERVIEW
The City of Beaumont (Beaumont) appeals the district court’s discretionary remand of pendent state claims. Beaumont asserts the district court had a mandatory duty to rule on the sufficiency of service of process before remanding the pendent state claims. We have no jurisdiction to review-the remand order pursuant to Beaumont’s appeal and decline to treat the appeal as a petition for writ of mandamus because the district court had discretion to remand all issues with regard to pendent state claims.
II.
FACTS AND PROCEDURAL HISTORY
This .action arose out of the execution of a search warrant by Beaumont police officers, *935 John Funston, Allen Whitson, and John Aeosta. During the search, plaintiff Daniel Lee’s father was killed and plaintiffs, Avril King and Brenda Walls, were allegedly wrongfully incarcerated. The plaintiffs filed this action based on state law tort claims and federal claims pursuant to 42 U.S.C. § 1983 in California state court against Beaumont and the police officers.
On April 26, 1991, the plaintiffs served process on Beaumont under Cal.Code of Civ. Proc. § 415.20(a) by delivering copies of the summons and complaint to the office of Robert Bounds (Bounds), the Beaumont City Clerk, leaving the copies with his secretary, and by mailing copies to Bounds on the same day. The plaintiffs also attempted to serve process on Officer Acosta by leaving copies of the summons and complaint at his place of employment, the City of Beaumont Police Department.
The defendants properly removed the ease to federal district court under 28 U.S.C. § 1441 based on the court’s original jurisdiction over the § 1983 claims, and its pendent jurisdiction over the state law claims. After removal, the dеfendants filed a motion for summary judgment arguing the district court lacked personal jurisdiction over them because service of process was improper. The parties stipulated to the dismissal of Officer Funston. The district court dismissed Officer Whitson because he never received service and Officer Aeosta because he never authorized any person or entity to accept service on his behalf nor was substitute service perfected by mail. The district court also dismissed the federal claims under 42 U.S.C. § 1983 finding there was no triable issue of material fact. Finally, the district court remanded the pendent state claims to state court. The district court did not specifically address the issue of whether service of process on Beaumont was proper before remanding the pendent state claims.
Beaumont appeals the district court’s remand order. It contends Fed.R.Civ.P. 4(j) and 81(c) required the district court to rule on the sufficiency of service of process upon it and that such a ruling was mandatory before the district court could exercise its discretion to remand the pendent state claims.

APPEALABILITY OF THE REMAND ORDER
We must first' address the issue of whether the remand order is reviewable. “If [the district court remands a case] on the ground that removal was improvident and without jurisdiction, 28 U.S.C. § 1447(c) (1982), the remand order ‘is not reviewable on appeal or otherwise.’ ”
Sever v. Alaska Pulp Corp.,
Even though the order is reviewable, we may review the order only pursuant to the proper type of review. “[T]he type of review available depends on the nature of the decisions made in the remand order.”
Sever,
As indicated, Beaumont filed an appeal requesting review of the . remand order. Beaumont asserts the district court’s discretionary remand order of pendent state claims is an order based on a substantive decision, and as a result, its ■ appeal was the proper procedure by which to obtain review of the order. Beaumont’s rationale is that the district court necessarily made a substantive decision when it determined there was no basis for the federal claims and dismissed them. It contends this substantive decision is relevant in determining the nature of the decision underlying the remand order. Beaumont’s contentiоn is incorrect. When a district court exercises its discretion not to hear pendent state claims the decision is a jurisdictional decision.

TREATING THE APPEAL AS A PETITION FOR WRIT OF MANDAMUS
As an alternative to reviewing the remand order pursuant to its appeal, Beaumont requests we construe its appeal as a petition for writ of mandamus. We have the discretion to treat an appeal as a petition for writ of mandamus' when appropriate.
See National Org. for the Reform of Marijuana Laws v. Mullen,
The Bauman test establishes five guidelines for determining whether a petition for writ of mandamus, or in this case mandamus jurisdiction, will be granted:
(1) The party seeking the writ has no other adequate means, such as a direct appeal, to attain the relief he or she desires.
(2) Thе petitioner will be damaged or prejudiced in a way not correctable on appeal. (This guideline is closely related to the first.)
(3) The district court’s order is clearly er-. roneous as a matter of law.
(4) The district court’s order is an oft-repeated error, or manifests а persistent disregard of the federal rules.
(5) The district court’s order raises new and important problems, or issues of law of first impression.
National Org. for the Reform of Marijuana Laws,
Beaumont fails to meet any of the
Bauman
guidelines. Because Beaumont has an adequate means by which it may attain relief, it fails to fulfill the first guideline. Although, as indicated earlier, Beaumont may not directly appeal the discretionary remand order of pendent state claims, it may raisе the issue of service of process in the state court litigation of the remanded pendent state claims. The issue of the sufficiency of service of process prior to removal is
*937
strictly a state law issue,
see Anderson v. Allstate Ins. Co.,
Beaumont fails to fulfill the second guideline because there is no evidence it will be prejudiced or damaged by allowing the state trial court to determine whether service of process was proper. Further, in thе event the state court were to incorrectly decide the issue, Beaumont may appeal in the state court system; thus, any potential prejudice or damage is correctable on appeal.
The district court’s remand order was not clearly erroneous because the district court had discretion to remand pendent state claims. We have often held that it is “within a district court’s discretion either to retain jurisdiction to adjudicate the pendent state claims or to remand them to state court.”
Harrell v. 20th Century Ins. Co.,
Under thе fourth guideline, the district court’s order is not an oft-repeated error because in fact there was no error committed by the district court. As already discussed, the district court-had discretion to remand the pendent state claims and all remaining issues relating to those claims. Beаumont argues the district court disregarded Fed.R.Civ.P. 4(j)
2
and 81(c)
3
by failing to rule on the service of process issue. However, nothing in the language of these rules requires the district court to rule on the sufficiency of service of process when the only viable claims are remanded pendent statе claims. Rule 4(j) does not apply to service of process which was attempted
prior to
removal; the sufficiency of service in this case is determined according to state law because service of process occurred before removal.
See Anderson,
Further, the district court did not err by assuming it had personal jurisdiction over Beaumont in order to reach and dismiss the fedеral claims asserted against Beaumont. A court may assume the existence of personal jurisdiction and adjudicate the merits in favor of the defendant without making a definitive ruling on jurisdiction.
Ashley v. Boehringer Ingelheim Pharmaceuticals,
*937 These rules apply to civil actions removed to the United States district courts from the state courts and govern procedure after removal.
*938 Finally, Beaumont fails to meet the fifth guideline. As noted earlier, frequently we have held the district court possesses the discretion to decline the exercise of pendent jurisdiction. Beaumont’s argument that the district court was mandated by the federal rules to exercise pendent jurisdiction and resolve the issue of service of process does not raise new, important problems or issues of law of first impression.'

CONCLUSION
Generally, we will review a district court’s discretionary remand order of pendent state claims only upon a petition for writ of mandamus. An appeal will be treated as a petition in extraordinary cases. This case does not present exceptional circumstances, for such treatment, and we decline mandamus jurisdiction.
APPEAL DISMISSED.
Notes
. 28 U.S.C. § 1447(c) was amended effective November 19, 1988, to provide for remand not when removal had been "improvident and without jurisdiction" but rather when it appeared that the district court was without subject matter jurisdiction. The new version was in effect at the time of the district court's remand order, but the amendment does not represent a substantive change for the purposes of this discussion.
. Fed.R.Civ.P. 4(j) states in relevant part:
If a service of the summons and complaint is not made upon a defendant within 120 days after the filing of the complaint and the party on whose behalf such service was required cannot show good cause why such service was not made within that period, the action shall be dismissed as to that defendant without prejudice upon the court’s own initiative with notice to such party or upon motion.
. Fed.R.Civ.P. 81(c) states in relevant part:
