Appellant Trimmings challenges by a writ of habeas corpus the computation of his present and prior sentences. He maintains that (1) the length of time he is being compelled to serve on his second sentence was improperly computed by the parole board; (2) the added confinement under the second sentence is defective because of the long lapse of time between the issuance of the violator's warrant on his first conviction and the parole revocation hearing seven years later; and (3) the sentence should have included a credit of pre-sentence jail time when he was denied bail due to the existence of a violator's warrant on his first conviction.

The District Court with great patience several times considered these complaints on their own and, in the light of an earlier case raising related issues, called on the Government by a show cause order to respond to specific issues, ultimately finding them without merit. We agree and affirm.

Appellant's history of arrests, sentences, and parole revocations form a checkerboard pattern extending back over the last 16 years.1

The answer is clear with respect to his claim that the remaining 542 days on conviction No. 1 (New Jersey) was improperly applied2 on the grounds that the execution of the 1962 violator's warrant (1(a)) should not have been delayed until 1970 (1(a)), and, therefore, the revocation lacked due process. First, we have repeatedly held that where a warrant has been properly issued within the maximum term of the sentence, the execution of that warrant may be held in abeyance for the service of an intervening sentence. Following many earlier cases we recently reiterated this in Cook v. United States Attorney General, 5 Cir., 1974, 488 F.2d 667. See also, Cox v. Feldkamp, 5 Cir., 1971, 438 F.2d 1; Smith v. Blackwell, 5 Cir., 1966, 367 F.2d 539.

Secondly, subsequent to the execution of the warrant (1(a)) there was a revocation hearing (1(b)) and there was no showing of any fundamental unfairness either from the delay or the procedures followed in the Morrissey3 sense. Cf. Cook v. United States Attorney General, 5 Cir., 1974, 488 F.2d 667.

This means that on the mandatory release date (12/13/70) under conviction No. 2 (New York) he was properly required to serve the 542 days remaining on conviction No. 1 (New Jersey). A part of this remained unserved when, on 12/10/71, a new mandatory release date arrived. (1(a))

Thereafter a new violator's warrant was issued on 7/6/72 and executed 1/30/73. (2(a)) This was followed by a local parole revocation hearing as to which there can be no procedural due process complaint. The Board fixed the time remaining at 1,382 days.4

This result was proper and is not defective either because the parole board aggregated the sentences5 or necessarily extended the date on which the substantive sentences would normally have expired.

Since revocation of mandatory release parole results in a loss of credit for time on parole, Henning v. United States Bureau of Prisons, 5 Cir., 1973, 472 F.2d 1221, the original sentence does not fix the calendar date of expiration of the sentence so that confinement beyond the original expiration date is permissible. Sturgis v. United States, 5 Cir., 1969, 419 F.2d 390.

The short answer to the claimed error in denying credit for jail term is that appellant having received less than the statutory maximum for conviction No. 2 (New York), Bryans v. Blackwell, 5 Cir., 1967, 387 F.2d 764 compels the presumption that the sentencing Judge took into account all jail time, both before and after, any use of the violator warrant (1(a)) as a detainer.

Affirmed.
