Envtl. Conservation Org. v. City of Dallas, 07-10583

In a suit brought under the Clean Water Act (CWA), summary judgment for the city is vacated and remanded for dismissal on mootness grounds where: 1) an EPA negotiated consent decree on a prior filed CWA citizen suit does not give rise to an immediate res judicata dismissal; 2) developments subsequent to the filing of a citizen suit may moot the citizen's case, requiring a jurisdictional mootness inquiry; 3) the court adopts the "realistic prospect" test for mootness; and 4) plaintiff failed to show a realistic prospect that any of the violations alleged in its suit will continue notwithstanding the consent decree.
