delivered the opinion of the Court.
This аction, involving a comprehensive zoning amendment by petitioner County Council for Prince George’s County, presents two essentially procedural issues for our consideration. On the one hand, the Council contends that this suit is not properly before us because respondent Carl M. Freemаn Associates, Inc., instituted it by way of administrative appeal when no such remedy is provided by law. On the other hand, the respondent asserts that the map amendment is invalid as a matter of law because it was approved by resolution instead of by ordinance. Although we reject the petitiоner’s contention, the Council loses only the battle — with a measure of last minute curative assistance from the General Assembly, it wins the war (at least in this Court) since we conclude that the respondent’s assertion that the amendment was invalidly approved is now moot.
The relevant facts arе not in dispute. In 1974 the petitioner, sitting as the District Council for the Maryland-Washington Regional District in Prince George’s County, initiated by Council Resolution CR-3-1974 a comprehensive rezoning of Planning Area 62, known as South Laurel-Montpelier. Pursuant to Section 30A.0 of the Zoning Ordinance for Prince George’s County, such rezоning is effectuated by an action of the District Council which is *73 passed as a Council Resolution and is known as a Sectional Map Amendment (SMA). Public hearings on the proposed SMA were held in the first seven months of 1975, and on August 5 of that year, following review and discussion of the record and several prоposed modifications, the District Council approved the South Laurel-Montpelier SMA with the adoption of Council Resolution CR-85-1975. Among the properties rezoned was that of the respondent.
Thirty days thereafter, on September 4, 1975, Freeman instituted an administrative appeal of the petitioner’s decision to the Circuit Court for Prince George’s County. The Council demurred, stating that the adoption of the SMA was “a purely legislative act from which no B-Rule appeal may be taken,” and that Freeman had “failed to exhaust administrative remedies,” but the demurrer was overruled. Latеr, respondent Freeman filed a motion for summary judgment in which it argued that CR-85-1975 was invalid because it was inconsistent with the relevant master plan. This motion was denied on September 28, 1976. However, on January 17, 1977, the trial court ruled in the respondent’s favor on one of several issues of law which were advanced for determination prior to a trial on the merits. On that day, the court concluded that approval of the SMA by council resolution rather than by ordinance was invalid under § 8-101 (b) of Article 66D, Md. Code (1957, 1970 Repl. Vol., 1976 Cum. Supp.), and granted judgment in favor of Freeman. The petitioner noted an appeal from this order, and Freeman cross-appealed from the court’s earlier order denying its motion for summary judgment. On March 8, 1977, we granted the Council’s petition for certiorari before decision in the Court of Special Appeals.
Initially, we consider whether this Court has jurisdiction to deсide the present case. 1 We conclude that we do, since it is clear that review of the petitioner’s decision adopting the SMA, by way of appeal to the Circuit Court for Prince George’s County, is authorized by Article 66D, § 8-106 (e), *74 and is governed by the provisions of Subtitle B of Chapter 1100 of the Marylаnd Rules. 2
As we have recently stated on several occasions, the B Rules do not grant a right of appeal, but merely set forth the procedures governing appeals otherwise provided by law.
See Mont. Co. v. One Park North,
The term “administrative agency,” as used in this Subtitle, shall mean any board, departmеnt, commission, authority, commissioner or other officer of the State or of a county or local government, whether appointed or elected, whether legislative, administrative, executive, ministerial or quasi-judicial, whose action or decision is specifically subject to court review, except by way of mandamus, by any provision now or hereafter set forth in any general or local statute, ordinance or regulation now or hereafter in effect; but shall not mean any court created by Article IV of the Constitution of Maryland.
Finally, it is plain that judicial review is “specially authorized by statute.” Sections 8-104 and 8-106 of Article 66D generally govern amendments to zoning regulations in *75 Prince George’s County, and as defined in § 8-106 (d), the word “amendment” obviously includes the SMA process involved in the present action:
(d) Definitions for sections. — For purposes of §§ 8-104, 8-105 and 8-106 herein, the word “amend” or “amendment” shall be deemed to include . . . any repeal or abolition of any map or part thereof, or any addition to any map, or any new map, or any other change in the map or maps.
Appeals from zoning amendment decisions are regulated by § 8-106 (e), which provides in pertinent pаrt:
(e) Appeals authorized. — In Prince George’s County, any incorporated municipality located in Prince George’s County, any person or taxpayer in Prince George’s County, the applicant who is an aggrieved party, may have judicial review of any final decision of the district council.
By broadly defining the word “amendment” and by using the words “any final decision” in the § 8-106 (e) appeals provision, the legislature 'expressed an intent that council resolutions adopting SMA’s be appealable in Prince George’s County. 3
The Council nonetheless suggests that the “any final decision” language of § 8-106 (e) should be construed so as not to apply to SMA decisions because such actions are “purely legislative.” We reject this suggestion. While it is true that comprehensive rezoning is essentially a legislative function,
Montgomery County v. Woodward
&
Lothrop, Inc.,
Having determined the jurisdictional issue, we now turn to the validity of the SMA challenged by this appeal. Although the petitioner’s decision was assailed on numerоus fronts in the circuit court, the court based its ruling on a single ground and did not reach most of the issues raised by the respondent. Determining that Article 66D, § 8-101 (b) mandates the enactment of SMA’s by ordinance, the judge concluded that CR-85-1975 was invalid because it was enacted by resolution. However, between the date of the court’s decision (January 17, 1977) and our decision today, the General Assembly enacted Chapter 283 of the Laws of 1977, a curative act which we believe has the effect of validating the Council’s action, regardless of whether prior to the passage of Chapter 283, § 8-101 (b) required SMA’s to be approved by ordinance.

Of course, we are bound to apply the law as it exists at the time a case is decided by this Court, so long as its application does not interfere with intervening vested rights,
Rockville Fuel v. Gaithersburg,
Chapter 283 of the Laws of 1977, repealing and reenacting with amendments Article 66D, § 1-105, provides:
Any zoning ordinance, regulation, resolution, amendment or change, report, zoning map, or other zoning action enacted, adopted, made, or taken prior to the еffective date of this act by the County Council of Montgomery County or the County Council of Prince George’s County, acting respectively as the district councils of the regional district, or by the Commission under any applicable laws, are approved, ratified, validated, and confirmed, notwithstanding any defect in the procedure followed in the enactment, adoption, making, or taking of such ordinance, regulation, resolution, amendment or change, report, zoning map, or other zoning action, or any failure strictly to conform to or comply with the procedure specified in the applicable laws; any zoning map amendment enacted by resolution prior to the effective date of this Act by the County Council of Montgomery County or the County Council of Prince George’s County, acting respectively as the district councils of the regional district are hеreby ratified, confirmed and validated.
Although this law was enacted as an emergency measure to take effect from the date of its passage, and was approved by the governor on April 29, 1977, the respondent posits, and the petitioner apparently concedes, that the bill failed to receive the three-fifths vote required of such measures by Article XVI, Section 2 of the Maryland Constitution. Freeman maintains that because of this fact, Chapter 283 is a nullity. Furthermore, it contends that even if the law is not void, it nevertheless is either not applicable to the *78 present аction or, if applicable, operates to deprive the respondent of its constitutional rights to procedural due process. We reject all of these contentions.
In the first place, so long as a bill is passed by a majority vote and is otherwise validly enacted, it is not а nullity merely because it is designated to be an emergency measure but fails to receive a three-fifths vote of both houses of the General Assembly. Pursuant to Article III, Section 31 of the Maryland Constitution, a law passed by the General Assembly takes effect on the June 1 following the legislative session unless otherwise expressly declared by the legislature or provided by the Constitution. Therefore, although Chapter 283 failed to become effective on April 29, 1977, as it would have had the bill received the requisite vote, the act nonetheless took effect on June 1, 1977.
See Allied American Co. v. Comm’r,
Secondly, we believe that Chapter 283 was intended to apply to the present case and may be applied without interference with any constitutional or vested rights of the
*79
respondent. Clearly, thе law was passed in order to validate zoning map amendments enacted by resolution, at least to the extent that such amendments may not be successfully attacked on the ground that they were adopted by resolution and not by ordinance.

We also conclude that the law is valid as аpplied in the present action. As Judge Singley, for this Court, recently stated in
Dryfoos v. Hostetter,
Although curative acts may be broadly characterized as being retroactive or retrospective in their operation, they are generally sustained on the theory that whatever a sovereign power mаy authorize in prospect, it may adopt and validate in retrospect, so long as there is no interference with vested rights or contractual obligations. [(Citations omitted.)]
This general rule restates what has been the law in Maryland for many decades.
See Leonardo v. County Comm.,
Concluding that it would be inappropriate at this time to pass on the propriety of the denial of the respondent’s summary judgment motion, and determining thаt further proceedings are required to resolve the other issues raised but not decided by the trial court, we shall vacate the judgment entered by the circuit court.
Judgment of the Circuit Court for Prince George’s County vacated and case remanded to that court for further proceedings. Costs to be paid one-half by the petitioner and one-half by the respondent.
Notes
. Although the respondent moved to dismiss the appeal on the ground that it was taken by an improper party, we find its motion to be without merit and consequently we deny it without further comment.
. We note that a further right of apрeal, from the circuit court to the Court of Special Appeals and to this Court, is also authorized by statute. Md. Code (1957,1970 Repl. Vol., 1976 Cum. Supp.), Art. 66D, § 8-106 (j); see Code (1974,1976 Cum. Supp.), Cts. & Jud. Proc. Art., § 12-201.
. We point out that when the legislature wished to authorize a more narrow right, as it did with respect to appeals in Montgomery County, it made plain that intent through the use of more restrictive language. Art. 66D, fj 8-105 (a) (authorizing appeals only with respect to applications for map amendments);
see
Hilland v. Montgomery Co.,
. Inasmuch as the petitioner has not argued before this Court that the respondent failed to exhaust other available administrative remedies before appealing pursuant to § 8-106 (e),
of.
Commission on Medical Discipline v. Bendler,
. We point out that the legislature, by Chapter 285 of the Laws of 1977, also repealed and reenacted with amendments § 8-101 (b) so as to permit a district council to amend zoning maps by resolution as well as by ordinance.
. Whether Chapter 283 has any further ramifications is a question we do not now decide.
