|(h) Injunctive Relief. The Commission may, upon making the
determination specified in subsection (g), bring suit in the United States
District Court for the District of Columbia to enjoin operation of the
agreement. The court may issue a temporary restraining order or
preliminary injunction and, upon a showing that the agreement is likely,
by a reduction in competition, to produce an unreasonable reduction in
transportation service or an unreasonable increase in transportation cost,
may enter a permanent injunction. In a suit under this subsection, the
burden of proof is on the Commission. The court may not allow a third
party to intervene with respect to a claim under this subsection.

(1) may order compliance;
(2) shall extend the period specified in subsection (c)(2) until there has been substantial compliance; and
