This is an interlocutory appeal from an allowance of the defendant’s motion to suppress evidence. The motion judge, holding that the search of an apartment pursuant to a validly issued warrant constituted a warrantless search due to the failure of the police to possess the warrant in hand at the commencement of the search, ordered the suppression of the evidence seized during the search. Because we agree that, under art. 14 of the Declaration of Rights of the Massachusetts Constitution, law enforcement officials are required to possess a copy of the warrant in hand when executing a search warrant, we affirm.
On September 11, 1991, a confidential informant told Boston police detective Timothy Lynch that a thirty year old, Hispanic male, weighing approximately 150 pounds, and being about five feet, six inches tall, would be leaving 10 Ernst Street, apartment 3, in the Jamaica Plain section of Boston and would be driving a blue motor vehicle with a particular registration number en route to deliver a package of cocaine. Later that day, Boston police detective William Tracy observed the defendant, Jose Guaba, who matched this description, leave the above address and drive away in the above described motor vehicle. The officers subsequently seized a package of cocaine from the defendant and placed him under arrest. Detective Lynch then travelled to the West Roxbury District Court to obtain a search warrant for 10 Ernst Street, apartment 3. Anticipating that a search warrant would be issued, the other officers proceeded to that address to secure the premises.
At the apartment, the police found Sandra Rodriguez and two young children. The police informed her that the defendant had been arrested and that they were seeking a search *748 warrant for the apartment. They did not conduct a search at this time. The police waited until they received a call from Detective Lynch informing them that a search warrant had been issued. The police then searched the apartment and seized cocaine, cash, and paraphernalia used to distribute cocaine. Before the search was completed, Detective Lynch arrived with the warrant. Subsequently, the defendant was indicted on charges of trafficking in cocaine in violation of G. L. c. 94C, § 32E (1992 ed.), and conspiracy to violate a controlled substance law in violation of G. L. c. 94C, § 40 (1992 ed.).
Prior to trial, the defendant moved to suppress the evidence seized during the motor vehicle search and the search of the apartment. After a hearing, the motion judge denied the motion concerning the evidence seized during the motor vehicle stop but allowed the motion concerning the evidence seized during the apartment search.

v. Rutkowski,
1. Commonwealth’s leave to appeal. The defendant argues that the single justice improperly allowed the Commonwealth’s application for leave to appeal because the Commonwealth failed to file its notice of appeal in a timely manner. The procedural facts follow.
On September 3, 1992, the motion judge filed a written memorandum containing her findings of fact, rulings of law, and order concerning the two suppression motions. On October 20, 1992, the Commonwealth filed a notice of appeal from the order suppressing the evidence seized from the apartment. In its motion, the Commonwealth stated its intent to seek leave to appeal the suppression order from the single justice of this court and asserted that it did not receive a copy of the judge’s written decision until September 22,
*749
1992. On this same date, the defendant filed a motion to dismiss the appeal, arguing that the Commonwealth had not filed the notice within the thirty-day period mandated by Mass. R.A.P. 4 (b), as amended,
The defendant argues that the Commonwealth was required by Mass. R.A.P. 4 (b) to file a notice of appeal in the Superior Court within thirty days after the suppression order on September 3, 1992. Thus, the defendant argues, the Commonwealth’s filing of the notice on October 20, 1992, was untimely and that, under our decision in
Commonwealth
v.
Bouvier,
The Commonwealth argues that its notice of appeal was timely in that it filed the notice within thirty days after it received a copy of the judge’s written decision on September 22, 1992. Supported by affidavit, the Commonwealth contends that the prosecutor was informed by a clerk in the Superior Court clerk’s office that the delivery of the written decision constitutes official notification of the decision and that the thirty-day period for filing a notice of appeal begins when the parties were so notified. The Commonwealth asserts that Mass. R.A.P. 4 is unclear as to when the thirty-day time period begins to run as to interlocutory motions and, hence, that it was justified in relying on the clerk’s advice. The *750 Commonwealth concedes that it knew before it received the written decision that the judge had granted the motion to suppress. In addition, the Commonwealth argues that, even if its notice of appeal is held to be untimely, the allowance of its application for leave to appeal should still be affirmed because its tardiness is excusable in light of its reasonable reliance on the clerk’s advice, the importance of the issue raised in this appeal, and the absence of any prejudice to the defendant. 1
We begin by stating that the single justice may have extended the Commonwealth’s time to file its notice of appeal under Mass. R.A.P. 2,
The Commonwealth has a right to apply to this court for an interlocutory appeal “from a[n] . . . order of the superior court determining a motion to suppress prior to trial.” G. L. c. 278, § 28E (1992 ed.). See
Commonwealth
v.
Bouvier, supra.
This section further provides that the “[rjules of practice and procedure with respect to appeals authorized by this section shall be the same as those applicable to criminal appeals under the Massachusetts Rules of Appellate Procedure.” Rule 15 (b) (2) of the Rules of Criminal Procedure
*751
also expressly provides for this right. The Commonwealth must file its application for leave to appeal “within such reasonable time after the ruling of the judge as the judge may allow and in any event before the defendant has been placed in jeopardy.” Mass. R. Crim. P. 15 (b) (3),
Although it is clear that the Commonwealth, when applying for leave to appeal a suppression order, must file a notice of appeal as required by rules 3 and 4, it is unclear as to when the thirty-day period begins to run. Rule 4 (b) expressly refers only to a verdict, finding of guilt, or imposition of the sentence and does not expressly refer to interlocutory appeals. In the interests of consistency and certainty, we hold that the notice of appeal for an interlocutory appeal from an order, under Mass. R.A.P. 4 (b), must be filed within thirty days after the order is filed. However, because we acknowledge that the rule was unclear as to interlocutory appeals and because we accept the Commonwealth’s assertions that it did not receive the written decision until nineteen days after the allowance of the defendant’s motion to suppress and that it relied upon the advice of the clerk, we hold that the Commonwealth’s notice of appeal was timely filed.

In the future, any delay in receiving the judge’s written decision
*752
will not be relevant in determining if the appellant has filed within the thirty-day period. Of course, a delay may be relevant in the determination of whether to extend the time to file the notice of appeal under either Mass. R.A.P. 4 (c) or Mass. R.A.P. 14 (b).

Additionally, Mass. R.A.P. 2 offers another potential avenue of relief.

A party should have “a reasonable period of time to study the judge’s decision to see if an appeal might have merit . . . .”

v.
Lewin (No. 3),
2. Absence of warrant at search. The Commonwealth asserts that the motion judge erred in ruling that the search of the apartment constituted a warrantless search. Pointing out that the statutes which set out the requirements for warrants fail to contain any express language requiring the police to possess a warrant at the beginning of a search, the Commonwealth argues that, under traditional principles of statutory construction, no such requirement should be inferred. In the alternative, the Commonwealth argues that the police’s failure to possess the warrant at the beginning of the search merely constitutes a technical error in the warrant’s execution, requiring suppression only upon a showing of prejudice to the defendant. It further argues that, because the warrant in this case authorized the police to seize drugs and because *753 drugs are readily identifiable as contraband, the police conducted the search within the scope of the warrant, resulting in no prejudice to the defendant.
The motion judge determined, and there is no contention otherwise, that the search was commenced after the issuance of the warrant and that the warrant was validly issued. Our inquiry is limited to whether police failure to possess the warrant in hand at the beginning of the search renders the search illegal and, if it does, whether suppression is required.
The Commonwealth correctly notes that neither art. 14 of the Declaration of Rights nor G. L. c. 276, §§ 1 et seq., contains any express language requiring law enforcement officials to possess a copy of a search warrant in hand when they commence a search pursuant to a warrant. The Commonwealth further notes that the jurisdictions which require the presence of the warrant at a search do so expressly by statute or court rule and generally characterize the requirement as directory or ministerial.

However, although we have never addressed this precise issue, we. have expressed the proposition that the presence at the search of documents describing the items to be seized is crucial in order for a warrant to meet the particularity requirements of art. 14 and G. L. c. 276, § 2. Furthermore, we have held that art. 14 “may, in some circumstances, provide more substantive protection to criminal defendants than does the Fourth Amendment” to the United States Constitution.
Commonwealth
v.
Amendola,
In
Commonwealth
v.
Rutkowski,
Just as the absence of the affidavit describing the items to be seized rendered the search in Rutkowski an unlawful search pursuant to a general warrant, the absence of the warrant should render the search in this case a warrantless search. The presence of the warrant at the search serves several purposes. The warrant guides law enforcement officials as to the permissible scope of the search, particularly describing both the area to be searched and the items to be seized. Furthermore, the presence of the warrant serves to put the occupant whose premises are to be searched on notice of the police’s authority to search and the reasons for the search. Not only were the officers without guidance as to the scope of the authorized search, as in Rutkowski, but also the occupant of the apartment was without notice as to the officers’ authority to search. Although many jurisdictions regard the failure of the police to possess the warrant at the commencement of the search as a technical error, mandating suppression only when the warrant’s absence prejudices the defendant, we view the omission as invalidating the reasonableness of the search. Even assuming that the officers were without the need of the warrant to guide them as to the items to be seized because the warrant in this case authorized the seizure of drugs, the warrant also guides the law enforcement officials as to which premises they are authorized to search. Furthermore, where a warrant is required, a search by law enforcement officials, even if conducted within the scope of the warrant, without the document exhibiting their authority to search is unreasonable per se. The failure of the police to possess a copy of the warrant when they commenced searching the apartment rendered the search warrantless.
As noted above, the judge determined that the search did not fall within any of the narrowly-drawn exceptions to the warrant requirement.

Forde,
So ordered.
Notes
The Commonwealth also argues that the defendant waived his argument concerning the propriety of the single justice’s granting leave to appeal in that he failed to file a memorandum in opposition to the Commonwealth’s application and waited over six months before filing a motion to reconsider. We have reviewed the record and conclude that, in these circumstances, the defendant sufficiently raised this issue below to raise it here.

For example, the United States Courts of Appeal have uniformly held that violations of Fed. R. Crim.
