Upon a certification by the Attorney General that the defendant was
acting in the scope of his employment at the time of the incident out of
which the suit arose, any such civil action or proceeding commenced in a
State court shall be removed without bond at any time before trial by
the Attorney General to the district court of the United States of the
district and division embracing the place wherein it is pending and the
proceeding deemed a tort action brought against the United States under
the provisions of title 28 and all references thereto. Should a United
States district court determine on a hearing on a motion to remand held
before a trial on the merit that the case so removed is one in which a
remedy by suit within the meaning of subsection (a) of this section is
not available against the United States, the case shall be remanded to
the State Court: Provided, That where such a remedy is precluded because
of the availability of a remedy through proceedings for compensation or
other benefits from the United States as provided by any other law, the
case shall be dismissed, but in the event the running of any limitation
of time for commencing, or filing an application or claim in, such
proceedings for compensation or other benefits shall be deemed to have
been suspended during the pendency of the civil action or proceeding
under this section.
