(c) Joinder of Federal law claims and State law claims.--(1) If a civil action includes--
(A) a claim arising under the Constitution, laws, or treaties of the
United States (within the meaning of section 1331 of this title), and
(B) a claim not within the original or supplemental jurisdiction of the
district court or a claim that has been made nonremovable by statute,
the entire action may be removed if the action would be removable
without the inclusion of the claim described in subparagraph (B).
(2) Upon removal of an action described in paragraph (1), the district
court shall sever from the action all claims described in paragraph
(1)(B) and shall remand the severed claims to the State court from
which the action was removed. Only defendants against whom a claim
described in paragraph (1)(A) has been asserted are required to join in
or consent to the removal under paragraph (1).
