OPINION
The defendant was convicted of robbery with a firearm and sentenced on October 23, 1979 to a term of not less than fifteen nor more than fifty-five years. On June 19, 1980, some eight months after defendant initially began serving his sentence, the district attorney filed a supplemental information alleging that the defendant had previously been convicted of armed robbery in 1971 and therefore his punishment for the second conviction should be life imprisonment in accordance with Section 30-16-2, N.M.S.A.1978. A trial was held on the supplemental information and the jury found the defendant to be the same person previously convicted in 1971. The trial judge therefore vacated the October 23, 1979 sentence and sentenced the defendant to life imprisonment. We affirm.
The defendant raises three points on appeal: (I) the enhancement procedure violated the defendant’s right to due process; (II) the resentencing of the defendant violated his constitutional protection against double jeopardy; and (III) the trial court erred in admitting penitentiary records that were not properly authenticated.
I. THE ENHANCEMENT PROCEDURE
The defendant was .sentenced under Section 30-16-2, N.M.S.A.1978, which reads as follows:
Robbery consists of the theft of anything of value from the person of another or from the immediate control of another, by use or threatened use of force or violence.
Whoever commits robbery is guilty of a third degree felony.
Whoever commits robbery while armed with a deadly weapon is, for the first offense, guilty of a second degree felony and, for second and subsequent offenses, is guilty of a first degree felony.
The statute provides no procedure for determining whether the defendant had previously been convicted of armed robbery, nor does it state how the defendant is to be informed of the possible sentence that he is facing if convicted. Since it is a procedural matter, it is within the province of the court to determine how this is to be accomplished.
We first address the issue of whether the filing of the notification of enhancement after conviction violates the defendant’s rights. The defendant argues that he is entitled to notice that he may be sentenced to life imprisonment as a second offender before he is tried on the robbery offense, claiming that anything else denies him due process. This Court has previously held that a defendant is entitled to notice of the charges by some pleading being filed and an opportunity to be heard before sentence is imposed. In State v. Rhodes,
[Ejssential fairness requires that there be some pleading filed by the state, whether it be by motion or otherwise, by which a defendant is given notice and opportunity to be heard before an increased penalty can be imposed.
The defendant in Rhodes appeared for sentencing and was questioned by the court as to whether he had previous convictions for narcotics violations. When the defendant admitted a prior conviction, the court immediately sentenced him as a second offender. On appeal, this Court held that there was a denial of due process in that procedure and that a pleading must be filed before enhancement could occur.
Rhodes did not address the issue as to whether filing of the pleading after conviction would violate due process. On this point, we see no difference between the procedure followed in the instant case and the filing of an habitual criminal proceeding under the habitual criminal statute. The separate enhancement proceeding has been approved by the United States Supreme Court in Oyler v. Botes,
II. DOUBLE JEOPARDY
The defendant claims that once he has begun his sentence that he cannot be resentenced and given an increased sentence. He relies, in particular, on State v. Allen,
There are many valid considerations, some evidentiary and some financial, for the district attorney to weigh before determining when an enhancement proceeding will be filed. And while we assume that in some case it could violate the defendant’s rights to wait a substantial period of time before enhancement is sought, that is not the case here. The appeal on the defendant’s conviction was not even affirmed until after the enhancement proceeding was filed.
As far as the claim that an increase in sentence amounts to double jeopardy, this court has held on a number of occasions that validly increasing a sentence under our habitual offender act is not double jeopardy. State v. James,
III. THE PENITENTIARY RECORDS
The third point that the defendant raises is that the records of the penitentiary that were used to prove his identity as previously convicted were improperly admitted. During the trial on the issue of identity, the judge admitted records from the penitentiary that were authenticated by the penitentiary’s records manager. The records were also under seal of the acting warden. The name typed on the form was that of “Robert E. Montoya”, however they were signed by “Felix Rodriguez, Acting Warden.” Since there was no foundation for the documents other than the documents themselves, they must be self-authenticating under Rule 902 of the Rules of Evidence, N.M.S.A.1978, in order to qualify as exceptions to the hearsay rule under Rule 803(8) of the Rules of Evidence, N.M. S.A.1978 (Cum.Supp.1980) which applies to public records. We hold that the exhibit was properly admitted. It was a document bearing the seal of a state agency, and it bears a signature of attestation. The typed name is irrelevant. The admission of evidence is within the discretion of the trial judge and will not be disturbed absent a clear abuse of discretion. State v. Valdez,
