OPINION OF THE COURT

We have before us only No. 98-1920. On January 30, 2002, we issued a Certificate of Appealability. It limited proceedings to the following:

“whether the District Court abused its discretion in failing to allow Petitioner to amend his 28 U.S.C. Section 2255 motion. In addition ... the parties should address (a) when, in light of the withdrawal and subsequent reinstatement of the direct appeal, did Petitioner’s ‘judgment of conviction become [] final’ for purposes of the statute of limitations; and (b) whether Petitioner’s motion to amend was timely.”

*581 The motion to amend referred to in the Certificate of Appealability is the motion filed August 27, 1998. In that motion, Fontanez said only the following with respect to the issues he sought to place before the Court by amendment:

“There are significant issues that have not been raised by counsel, of record, in the instant petition which petitioner Fontanez vehemently believes will conclusively support the ‘ineffective-assistance-of-counsel’ claim and will further support a vacation of the Judgment of Conviction insofaras (sic) the verdict was rendered on evidence that was unconstitutionally sound.

Petitioner Fontanez’s most significant issue that must be posited before this Court is ‘actual innocence’ and counsel has failed to raise same, with support of evidence that has not been presented before to this Court in previous proceeding(s).”

On October 6, 2004 we denied a motion to expand the Certificate of Appealability in No. 98-1920. We ruled at that time that Fontanez’s “new perjury claims [were] beyond the scope of this appeal” and that these “perjury claims had not been raised in the [District Court] at the time of the 98-1920 appeal.” The issue before us thus has nothing to do with the perjury claims Fontanez currently seeks to pursue. Rather, the sole issue before us is whether the District Court abused its discretion in not granting permission to amend in response to Fontanez’s August 27, 1998 filing. We hold that it did not.

While Fed.R.Civ.P. 15 provides that leave to amend “shall be freely granted when justice so requires,” one seeking to amend must provide the Court with sufficient information to allow it to determine whether justice does so require. The Court, for example, must be able to determine such matters as whether the amendment sought would be futile or unduly prejudicial to the opponent. . When the application to amend provides only conclusory statements like the “evidence ... was unconstitutionally sound” and “actual innocence,” the Court is not able to fulfill its responsibilities under Fed.R.Civ.P. 15, and it does not abuse its discretion if it denies the application. 1

The judgment of the District Court will be affirmed.
