unreasonable discrimination
(2) (A) A complaint may be filed under this subsection— (i) by a shipper on the grounds that such shipper individually will be harmed because the proposed contract unduly impairs the ability of the contracting rail carrier or carriers to meet their common carrier obligations to the complainant under section 11101 of this title ; or (ii) by a port only on the grounds that such port individually will be harmed because the proposed contract will result in unreasonable discrimination against such port. (B) In addition to the grounds for a complaint described in subparagraph (A) of this paragraph, a complaint may be filed by a shipper of agricultural commodities on the grounds that such shipper individually will be harmed because— (i) the rail carrier has unreasonably discriminated by refusing to enter into a contract with such shipper for rates and services for the transportation of the same type of commodity under similar conditions to the contract at issue, and that shipper was ready, willing, and able to enter into such a contract at a time essentially contemporaneous with the period during which the contract at issue was offered; or (ii) the proposed contract constitutes a destructive competitive practice under this part. In making a determination under clause (ii) of this subparagraph, the Board shall consider the difference between contract rates and published single car rates. (C) For purposes of this paragraph, the term “unreasonable discrimination” has the same meaning as such term has under section 10741 of this title .
