Trustees for Michigan Carpenters Council Pension Fund v. W.W.A. Inc., 2000 U.S. App. LEXIS 6416 (6^th Cir. Mar. 23, 2000) (unpublished)-The trustees for a pension fund alleged, and the district court agreed, that WWA was delinquent on its contributions to the Health and Welfare Fund and the Pension Fund for March, April, and May of 1998.  The court found, however, that in relation to alleged delinquent pension benefits, the WWA was current in its contributions as of August 28, 1998.  Since the Trustees demonstrated no irreparable harm in that respect, the district court denied injunctive relief.  This court declined to require a showing of irreparable harm in all cases, but otherwise summarily affirmed the district court's decision for no abuse of discretion.
