v.
TOWN OF MOUNT DESERT et al.
Docket: Han-10-177.
Supreme Judicial Court of Maine.
Submitted on Briefs: September 23, 2010.
Decided: November 2, 2010.
*663 Durward W. Parkinson, Esq., Leah B. Rachin, Esq., Bergen & Parkinson, LLC, Kennebunk, ME, for the Town of Mount Desert.
Clifford H. Goodall, Esq., Dyer Goodall and Denison, P.A., Augusta, ME, for Eugene E. Aubry and Janet C. Aubry.
Panel: SAUFLEY, C.J., and ALEXANDER, LEVY, MEAD, and JABAR, JJ.
SAUFLEY, C.J.
[¶ 1] This case involves a straightforward question: Can an existing restaurant in the Town of Mount Desert provide outdoor seating to its patrons? In the four years since the restaurant owner applied to the Town for authorization to provide that outdoor seating, the matter has been addressed by the Town's Planning Board, the Town's Zoning Board of Appeals, the Superior Court, and us on multiple occasions. In the middle of the process, when the restaurant owner appealed to us in 2008, we dismissed the appeal and remanded it to the Town because the Town had not completed its adjudication, and therefore the appeal was interlocutory. Brickley v. Horton, 2008 ME 111, ¶ 10, 951 A.2d 801, 803. Here, once again, we are confronted with an appeal challenging an order of the Superior Court (Hancock County, Cuddy, J.) remanding the matter to the Town, and, as before, we must dismiss the appeal and return the case to the Town for further action.

I. BACKGROUND
[¶ 2] We begin by summarizing the lengthy history of the permit application process in this matter:
September 2006   Kim P. Horton and Jean-Paul
                 Taillon applied to the Town of
                 Mount Desert Planning Board for
                 a conditional use permit to include
                 additional outdoor seating at
                 Horton's restaurant.
October 2006     The application was approved
                 with the condition that the last
                 seating in the outdoor patio would
                 be at 8:30 p.m.
March 2007       Two abutters appealed from the
                 decision on the ground that they
                 were not given the required notice
                 of the public hearing on the application.
                 See Brickley, 2008 ME
                 111, ¶ 5, 951 A.2d at 802.
April 2007       The Town's Zoning Board of
                 Appeals affirmed the conditional
                 approval. See id. ¶ 6, 951 A.2d at
                 802.
November 2007    Upon appeal by the abutters, the
                 Superior Court vacated the decision
                 of the Zoning Board of
                 Appeals and remanded the
                 matter for notice to the abutters
                 and a rehearing on the merits.
                 See id. ¶¶ 7-8, 951 A.2d at 802.
July 2008        Upon Horton and Taillon's appeal
                 to us from the Superior Court's
                 order of remand, id. ¶ 8, 951 A.2d
                 at 802, we dismissed the appeal
                 because there was no final judgment,
                 id. ¶¶ 9-10, 951 A.2d at 802-03.
March 2009       The Planning Board held a de
                 novo hearing and granted an
                 amended conditional use permit
                 containing several conditions related
                 to the hours and activities
                 allowed in the proposed outside
                 deck area.
April 2009       Horton appealed from this decision
                 to the Zoning Board of
                 Appeals, challenging the imposition
                 of the conditions.
May 2009         The Zoning Board of Appeals held
                 a public hearing and affirmed the
                 decision of the Planning Board.
June 2009        Horton appealed to the Superior
                 Court from the decision of the
                 Zoning Board of Appeals.
March 2010       After substituting Eugene E. and
                 Janet C. Aubry  who had meanwhile
                 purchased the restaurant
                 from Horton  as the plaintiffs,
                 the Superior Court concluded that
                 two sections of the Town's land
                 use ordinance were unconstitutionally
                 vague and represented an
                 unconstitutional delegation of legislative
                 authority. The court declared
                 the conditional use permit
                 issued in 2006 and the conditional
                 use permit on appeal to be void
                 and remanded the matter to the
                 Zoning Board of Appeals for remand
*664
                 to the Planning Board to
                 decide whether, and under what
                 conditions, to issue a permit based
                 on the remainder of the
                 Ordinance.
[¶ 3] Before the Planning Board could act on the remand order, the Town appealed from the Superior Court's order.

II. DISCUSSION
[¶ 4] Neither party has argued that this appeal is interlocutory. Both the Town and the Aubrys recognize, however, that the Superior Court's order directs the Town's Planning Board to engage in additional decision-making.[1] Whether or not either party raised the issue, however, we will dismiss an appeal sua sponte "if we determine that the appeal is unripe because the ... decision is not final." Brickley, 2008 ME 111, ¶ 9, 951 A.2d at 802. "A final judgment or final administrative action is a decision that fully decides and disposes of the entire matter pending before the court or administrative agency, leaving no questions for the future consideration and judgment of the court or administrative agency." Id. (quotation marks omitted).
[¶ 5] Because the Superior Court remanded this matter to a municipal decision-maker for further proceedings, the judgment is not final and may be appealed only if an exception to the final judgment rule applies. See id. ¶ 10, 951 A.2d at 803. There are "three exceptions to the rule that only final judgments are appealable: the death knell, collateral order, and judicial economy exceptions." E. Perry Iron & Metal Co. v. City of Portland, 2006 ME 52, ¶ 7, 896 A.2d 956, 958. None of these exceptions apply in this matter, however. The death knell exception does not apply because the Town does not stand to "irreparably lose any substantial rights if review is delayed until final judgment." Id. The collateral order exception does not apply because "the order at issue is not separable from and collateral to the underlying lawsuit." Id. ¶ 7, 896 A.2d at 959 (quotation marks omitted). Finally, the judicial economy exception does not apply because the appeal will not "establish a final, or practically final, disposition of the entire litigation," id. (quotation marks omitted), and the interests of justice do not require that immediate review be undertaken. See York Cnty. Bd. of Realtors v. York Cnty. Comm'rs, 634 A.2d 958, 960 (Me.1993). There are a number of ordinance sections that may apply to the permit application and could have an effect on the outcome of the permit application. See, e.g., Mount Desert, Me., Land Use Zoning Ordinance §§ 5.4, 6.6 (Mar. 7, 2006) (authorizing the imposition of conditions based on a proposed conditional use's compatibility with the permitted uses in the district).
[¶ 6] We do not entertain interlocutory appeals from orders that remand for additional municipal decision-making unless an exception to the final judgment rule applies. See Brickley, 2008 ME 111, 951 A.2d 801; Peaker v. City of Biddeford, 2007 ME 105, 927 A.2d 1169; Griswold v. Town of Denmark, 2007 ME 93, ¶¶ 16-18, 927 A.2d 410, 416-17; E. Perry Iron & Metal Co., 2006 ME 52, 896 A.2d 956; *665 Malonson v. Town of Berwick, 2003 ME 148, 838 A.2d 338; Doggett v. Town of Gouldsboro, 2002 ME 175, 812 A.2d 256. An unripe appeal, followed by our necessary dismissal, needlessly consumes additional time and resources. With a process that is already complexinvolving Planning Board hearings, full Zoning Board of Appeals review,[2] and review by the Superior Courtwe urge parties involved in municipal proceedings to carefully review the issue of finality before appealing from an order that remands a matter to another decision-maker.
[¶ 7] In summary, because the Superior Court remanded this matter for the Planning Board to reconsider the application for a conditional use permit, the judgment is not final. No exception to the final judgment rule applies. We dismiss the appeal as unripe and interlocutory.
The entry is:
Appeal dismissed.
NOTES
[1]  The Town acknowledges in its brief that the court "remanded the matter back to the Planning Board." In its reply brief, it further asserts: "On remand, the Planning Board will almost certainly impose identical conditions based on other applicable ordinance provisions." The Aubrys also recognize in their brief that the Superior Court "remanded the matter back to the Mount Desert Zoning Board of Appeals for a remand back to the Planning Board `to issue a Conditional Permit, as may be necessary and authorized under the Land Use Zoning Ordinance of Mount Desert consistent with the remaining ordinance and this opinion.'"
[2]  Although the review by the Zoning Board of Appeals is not a de novo review, this second level of municipal review does require an additional public hearing. See Mount Desert, Me., Reorganization of the Zoning Board of Appeals § 4(A)(1), (D) (Mar. 7, 2001). Should it choose to do so, the Town has the authority to amend its Ordinance to minimize delays in adjudication by, for instance, providing for direct appeal from the Planning Board to the Superior Court in its municipal ordinance. See 30-A M.R.S. § 4353(1), (2) (2009); see also 30-A M.R.S. §§ 3001-3014 (2009) (governing municipal ordinance authority).
