Petitioner appeals from the denial by the District Court for the District of Puerto Rico of a petition for habeas corpus. At present, he is serving a sentence of life imprisonment for a conviction of first degree murder arising out of a crime committed in 1943. Petitioner unsuccessfully appealed his conviction to the Supreme Court of Puerto Rico, People v. Rivera Escute,
In his 1965 petition to the Puerto Rican Supreme Court, petitioner was succesful in persuading the court to adopt the doctrine of Escobedo v. Illinois,
Petitioner argues, however, that the 1965 Puerto Rican case was not merely the application of the federal law as expressed in
Escobedo
to Puerto Rico, but rather that the Puerto Rican court was applying the Puerto Rican constitution and was using the
Escobedo
opinion as an analogous precedent. He argues further that in habeas corpus cases, the Puerto Rican Supreme Court has the same status as a United States district court, that a United States district court cannot, because of the case or controversy requirement, create new law without applying it to the case under consideration, and that the ruling in the 1965 case must therefore apply to petitioner. Petitioner does not argue that the Puerto Rican courts are Article III courts and hence bound by the case or controversy requirement of the United States Constitution,
cf.
Great Northern Railway Co. v. Sunburst Oil & Refining Co.,
We cannot understand how this statutory authority granted by Congress in the exercise of its powers over territorial possessions converts the Puerto Rican courts into federal Article III courts in habeas corpus eases only. Such a ruling would have the anomalous effect of preventing the Commonwealth courts from giving solely prospective effect to cases depending upon the random factor of how the cases came before the court. Moreover, the grant of power does not say that the Puerto Rican courts’ authority to issue writs of habeas corpus is limited in exactly the same way that district courts’ power is by the case or controversy requirement. The grant of subject matter jurisdiction to decide cases of persons who claim that they are unlawfully imprisoned, does not imply that the courts have no power to issue advisory opinions in those cases. The authority of the Puerto Rican Supreme Court to give only prospective effect to its rulings is dependent on the power granted that court by the Puerto Rican constitution, and that court is the authoritative interpreter of that constitution. We may sympathize with petitioner who has urged the issue of right to counsel at interrogations for so many years only to be denied the benefits of his efforts, but we cannot say that the Puerto Rican Supreme Court had no authority to issue a prospective ruling.
At oral argument, petitioner stressed an additional point. The interview at which petitioner made his confession was sometimes referred to in the record as a “preliminary examination”. Recently, the Supreme Court has ruled that a “preliminary hearing” is a critical stage of the prosecution at which the defendant’s right to counsel attaches. Coleman v. Alabama,
Normally, prosecutorial interrogations, while governed by
Escobedo
and
Miranda,
are not considered preliminary hearings. A preliminary hearing, such as the Alabama procedure at issue in
Coleman,
seeks to determine if there is sufficient probable cause to allow the state to bring the accused to trial.
Coleman, supra,
All confrontations between prosecutors and defendants were not, of course, preliminary hearings. From our examination of the record, we have determined that the prosecutor was not acting in his magisterial capacity when petitioner confessed. The only support for petitioner’s claim is that the prosecutor possessed magisterial powers and that the prosecutor placed him under oath before he took his statement. There were

no other witnesses examined

; there was apparently no bail set; the prosecutor apparently did not issue a warrant of arrest, petitioner having been earlier arrested and in custody; and there is no suggestion or evidence that the prosecutor made a formal determination of probable cause. That the proceeding was merely part of the investigation is not only indicated by contemporary references at the trial, but demonstrated by events. Petitioner had been taken into custody and had made several similar oral confessions to the police before the prosecutor was called in. The prosecutor appeared with a secretary and immediately issued warnings and commenced the questioning appearing in the written statement. The formal questioning began in the Detective Bureau Headquarters, was suspended while the petitioner led the prosecutor to various places in retracing his activities on the day of the crime, and was resumed and completed at the Loifza Street Police Station. Furthermore, on his original appeal and when petitioner made his first attempt to secure a writ of habeas corpus, he apparently argued that his conviction was improper because he had been denied a preliminary hearing. The Puerto Rican Supreme Court on two occasions and this court on appeal held that his conviction was proper even though he had been prosecuted on an information which had
not
been preceded by a preliminary hearing conducted by the district attorney.
See
People v. Rivera Es-cute,
Even if the interrogation had taken place at a preliminary hearing, we would be inclined to reach the same result. In
Coleman
the Supreme Court pointed to four factors which prompted it to decide that the accused needed the presence of an attorney. The attorney might point out flaws in the state’s case by examining witnesses, might obtain impeachment evidence or preserve favorable testimony for trial, might discover the state’s case, and might make effective arguments for lower bail or the necessity of an early psychiatric examination. Clearly the first three factors would have benefitted this defendant not at all since there were no other witnesses at the examination but himself. We are inclined to doubt the ability of a defense lawyer to persuade a magistrate to lower bail when the magistrate is also the prosecutor. Petitioner obtained a psychiatric examination before trial, and there was no prejudicial delay, the trial having taken place six months after petitioner’s arrest. In short, it would seem that the presence of a defense attorney might have served only to prevent a confession at the examination, but even here, petitioner was not prejudiced. On at least three separate occasions before he confessed to the prosecutor he had confessed to various police officers. This court has already ruled that none of these confessions was coerced. Rivera Escute v. Delgado,
Affirmed.
Notes
One witness, Pacheco, stated that he testified under oath before the prosecutor on an occasion when petitioner was in another room. There is no suggestion that this occurred in connection with the questioning of petitioner.
