United States Court of Appeals FOR THE EIGHTH CIRCUIT ___________ No. 00-2817 ___________ R. Alton Bowden, on behalf of * himself and all others similarly * situated; Wanda Martin Barrett, on * behalf of herself and all others * similarly situated, * * Appellants, * * Appeal from the United States v. * District Court for the Western * District of Arkansas. John E. Peterson, Jr., Individually and * as Trustee of The Lane Processing * [UNPUBLISHED] Trust; Edward H. Covell, Individually * and as Trustee of The Lane Processing * Trust; Walter W. Minger, Individually * and as Trustee of The Lane Processing * Trust; Lane Processing Trust, * * Appellees. * ___________ Submitted: March 16, 2001 Filed: March 21, 2001 ___________ Before RICHARD S. ARNOLD, FAGG, and MORRIS SHEPPARD ARNOLD, Circuit Judges. ___________ PER CURIAM.  Beneficiaries of a business trust brought this diversity-related action against the trustees alleging they breached their fiduciary duties by making distributions to some but not all of the trust's intended beneficiaries. The district court* granted summary judgment to the trustees. The district court recognized the trust document granted the trustees "sole and absolute discretion" to manage the trust property, including payment of trust income to "any one or more (whether all or less than all) of the members of the group consisting of the Beneficiaries," and held as a matter of law that the trustees did not breach their fiduciary duty in exercising their discretion. On appeal, the beneficiaries argue the district court committed error in granting summary judgment because there are genuine issues of material fact and the court denied them meaningful discovery. The beneficiaries also contend the district court should have granted their request for class certification. We review a grant of summary judgment under a well-established standard. Because this is a diversity action, we review de novo questions of state law. Having considered the record and the parties' briefs, we are satisfied the district court correctly applied the controlling state law, and the record supports the district court's summary judgment ruling. We also reject the beneficiaries' contention that the district court should have granted their request for class certification. Because the parties' submissions show they are thoroughly familiar with the issues before the court, we conclude that an extensive discussion in this diversity case would serve no useful purpose. We thus affirm on the basis of the district court's well-reasoned rulings without further discussion. See 8th Cir. R. 47B. * The Honorable Jimm Larry Hendren, United States District Judge for the Western District of Arkansas. -2- A true copy. Attest: CLERK, U.S. COURT OF APPEALS, EIGHTH CIRCUIT. -3-
