The district court denied Rener's petition for writ of error coram nobis. We affirm.

Rener is confined in the Texas Department of Corrections by virtue of his convictions for attempted burglary and possession of narcotics. In his petition for coram nobis relief he sought to have a previously served federal conviction vacated on grounds that the 1952 conviction for possession of untaxed marihuana1 was invalid under the decision of Leary v. United States, 1969, 395 U.S. 6, 89 S. Ct. 1532, 23 L. Ed. 2d 57.

The district court denied relief, finding that Rener had failed to present any "compelling circumstances" which would justify the grant of the extraordinary remedy of coram nobis.2 We agree.

Nowhere in the pleadings filed below did Rener allege that he is subject to any adverse effects emanating from the prior federal conviction. On the basis of the respondent's answer filed in the district court stating that Rener was convicted and sentenced on four felony offenses subsequent to the 1952 conviction, it appears unlikely that such is the case. The writ of error coram nobis should only be allowed to remedy manifest injustice. Cf. Reyes Correa-Negron v. United States, 5 Cir. 1973, 473 F.2d 684. Its purpose is not to burden courts with the rendition of "futile decrees." Rodgers v. United States, 5 Cir. 1971, 451 F.2d 562, 563; United States v. Morgan, 1954, 346 U.S. 502, 74 S. Ct. 247, 98 L. Ed. 248.

For the first time on appeal, Rener attempts to raise the point that the 1952 conviction was used to enhance his present state sentence. We decline to consider this argument since the issue was never raised in the proceedings below. Reyes Correa-Negron v. United States, supra; United States v. Hall, 5 Cir. 1971, 440 F.2d 1277; Hemming v. United States, 5 Cir. 1969, 409 F.2d 11.

The judgment appealed from is affirmed.

Affirmed.
