Appellees were charged with gambling, poolselling, bookmaking, and related offenses. The lower court granted their suppression motion on the basis that the search warrant had been improperly issued. The Commonwealth filed this appeal.
It is settled that the Commonwealth may only appeal from a pre-trial order suppressing evidence if two requirements are satisfied: the appeal must involve a pure question of law, and the suppression must effectively terminate or substantially handicap the prosecution. See Commonwealth v. Barnett, 471 Pa. 34, 369 A.2d 1180 (1977); Commonwealth v. Ray, 448 Pa. 307, 292 A.2d 410 (1972); Commonwealth v. Bosurgi, 411 Pa. 56, 190 A.2d 304 (1963); Commonwealth v. DeFelice, 248 Pa.Super. 516, 375 A.2d 360 (1977). The second requirement was stated in Commonwealth v. Bosurgi, supra, 411 Pa. at 63-64, 190 A.2d at 308, as follows:
From the point of view of the Commonwealth, two possible situations may arise: (a) the order of suppression will result in a termination and conclusion of the prosecution or (b) while the order of suppression will not result in a termination or conclusion of the prosecution, it will result in a prosecution wherein the Commonwealth is substantially handicapped because it cannot present all its available evidence.
It is, however, not settled how the Commonwealth is to show that it is “substantially handicapped”; indeed our cases are *8in conflict, and before we may decide this case they must be reconciled.

In Commonwealth v. DeFelice, supra, the majority of this court, per HOFFMAN, J., held that an appeal will be quashed where we determine from our examination of the record that the suppression order does not in fact terminate or substantially handicap the prosecution. In Commonwealth v. Trefry, 249 Pa.Super. 117, 375 A.2d 786 (1977), the majority, per PRICE, J., held that the bare allegation by the Commonwealth that it would be substantially handicapped was sufficient to assure appellate review.
These tests appear irreconcilable: Judge PRICE’S test is satisfied by a bare allegation; Judge HOFFMAN’s test requires a factual finding from the record. This appearance of irreconcilability is further manifested by the conflicting opinions in Commonwealth v. Deren, 233 Pa.Super. 373, 337 A.2d 600 (1975). There, the dissenting opinion, by SPAETH, J., joined by JACOBS, J., concluded that the record did not support the conclusion that the prosecution would be substantially handicapped. Id., 233 Pa.Super. at 383-89, 337 A.2d at 605-608. The majority opinion, however, by PRICE, J., held that
we must accept such an appeal as the Commonwealth’s good faith certification that the case will be terminated or substantially prejudiced .
To apply any other test could permanently exclude evidence even if it was improperly suppressed.
Id., 233 Pa.Super. at 378, 337 A.2d at 602.
Upon reflection, however, and with a little pushing and pulling, these apparently irreconcilable tests may be reconciled.
In its opinion, the majority in Commonwealth v. Deren, supra, says this:
An appellate review of the validity of the order of suppression cannot harm the defendant whereas the denial of the right to such review does harm the Commonwealth. *9Id., 233 Pa.Super. at 377, 337 A.2d at 602 (emphasis added).
Thus, despite its statement about having to “accept . an appeal as [a] . good faith certification,” the majority in Deren recognized the need for a factual finding, that is, for a finding that the suppression order “does harm” the prosecution. Indeed, this recognition was compelled by the principle that this court must always determine for itself that in fact it has jurisdiction to hear the case; jurisdiction may never be conferred by one, or both, of the parties, Commonwealth v. Yorktowne Paper Mills, Inc., 419 Pa. 363, 214 A.2d 203 (1965), as would be the case were we to accept a bare allegation of substantial handicap, that is, a bare allegation that we had jurisdiction.1
The question, therefore, is: How is this court to make the factual finding that the suppression order “does harm” the Commonwealth? The majority opinion in Commonwealth v. DeFelice, supra, holds that we must be able to make the finding by reference to the record of the suppression hearing. The majority opinion in Commonwealth v. Deren, supra, may be read as saying that we may make the finding without reference to the record, and simply on the basis of the Commonwealth’s bare allegation; it is not necessary, however, to read the opinion in this way.
An opinion, like any other statement, should always be read in light of the reason given in its support. In Commonwealth v. Deren, supra, the majority alluded to the danger that if we did not accept the Commonwealth’s bare allegation, we might “permanently exclude evidence even if it was improperly suppressed.” Id., 233 Pa.Super. at 378, 337 A.2d at 602. In fact, however, that danger can easily be avoided by a slight modification of the holding in Commonwealth v. DeFelice, supra.
*10If, when the appeal is filed, the record already shows that the suppression will terminate or substantially handicap the prosecution, there is no problem; the appeal is proper. This will often be the case, as, for example, when the district attorney makes a statement of record, before the judge hearing the motion to suppress, that the Commonwealth’s only evidence is the evidence that the defendant seeks to have suppressed. Or that fact may otherwise appear of record, as for example in the testimony of the arresting officer. In such circumstances the Commonwealth need only direct our attention to the record by appropriate references in its brief.
Cases that might seem more difficult are those in which the record before the hearing judge does not show that the suppression will terminate or substantially handicap the prosecution. In fact, however, these cases do not present either a different problem or a problem that may not be easily solved. All the Commonwealth need do is include in its brief a brief explanation why the suppression will terminate or substantially handicap the prosecution: for example, that it has no eyewitnesses; or that it does have an eyewitness but the witness’ opportunity to observe was so brief that without the results of the breathalyzer test, or the fingerprints, or whatever the evidence in question is, the prosecution will be substantially handicapped.
Accordingly, we now hold that in every case in which the Commonwealth appeals from an order suppressing evidence, the Commonwealth must include in its brief, in support of its claim that this court has jurisdiction to hear the appeal, first, a statement that the suppression will terminate or substantially handicap the prosecution; and second, a brief explanation, not inconsistent with the record, why this is so.
This holding is not so strict as the holding in Commonwealth v. DeFelice, for the Commonwealth’s statement of why the prosecution will be terminated or substantially handicapped need not be (although it may be) based on the record. At the same time, this holding avoids both the *11danger of exclusion, alluded to in Commonwealth v. Deren, and the impropriety of accepting jurisdiction on the basis of one party’s bare, that is, conclusory and unexplained, allegation of jurisdiction.

Here, appellees successfully argued to the lower court that the warrant was improper in that it had been issued to police officers acting outside of their jurisdiction. The suppression hearing, the lower court’s opinion, and the briefs filed with this court, all focus on this issue, without any explanation or amplification of the facts. The only facts that appear are that pursuant to information received from an informant, a search warrant was issued for appellee Kunkel’s residence, and that various gambling paraphernalia, such as note pads, telephones, and telephone bills, were found and seized there. It was these paraphernalia that were suppressed. There is no allegation in the Commonwealth’s brief to us — not even a bare, or conclusory, allegation, much less an allegation accompanied by an explanatory statement — that the suppression will terminate or substantially handicap the prosecution. Whether the Commonwealth has other evidence, such as the testimony of an eyewitness, does not appear. In these circumstances we have nothing from which to make a finding, either that we do, or that we do not, have jurisdiction to hear the appeal. Accordingly, we shall defer decision so that the Commonwealth may file a supplemental brief stating, as held in this opinion, first, whether the suppression will terminate or substantially handicap the prosecution, and second, if it will, why.
It is so ordered.
WATKINS, former President Judge, did not participate in the consideration or decision of this case. JACOBS, President Judge, concurs in the result. HOFFMAN, J., files a dissenting opinion. PRICE, J., files a dissenting opinion in which VAN der VOORT, J., joins.. Since the court reserves the right to raise the issue of its own jurisdiction, see, e. g., Davidyan v. Davidyan, 229 Pa.Super. 495, 327 A.2d 139 (1974), the fact that no party has moved to quash an appeal is not determinative. Cf. Commonwealth v. DeFelice, supra, 248 Pa.Super. at 368, 375 A.2d at 366 (dissenting opinion).
