Plaintiff rocks its damages model.

“[Kansas City] Southern [Railway] was caught between hundreds of thousands of tons of rock and a hard place.”  Problems with the construction of a new rail line in South Texas resulted in a dispute about payment for 74,260 tons of “rail ballast” – crushed stone that forms the base for the train tracks. The railway won the resulting litigation against its contractor, and the Fifth Circuit rejected several rocks thrown at the damages model, observing:

• Acknowledging that the payments made had to be reasonable, the Court reminded that “magic words” are not needed, and found that on this record: “Reasonableness can thus be demonstrated by the general market prices Southern was paying for these expenses before it had any knowledge that some excess ballast costs would be passed on to Balfour via litigation.
• Evidence of post-breach costs was appropriate, as the substantive damage calculation looks at the difference between “what Southern expected” and “the cost Southern ultimately had to pay (value received)”;
• Southern acted appropriately, and the defenses of waiver and quasi-estoppel did not apply: “It could have refused to ship additional ballast at Balfour’s request, but that would have necessitated stopping the project, finding a new contractor, and
  resuming later, all of which likely would have cost substantially more than the
  damages awarded here. Southern had a duty to mitigate as much as possible.
  It did so by allowing Balfour to finish the project and then determining the
  extent of damages.”

Concluding that the record was rock-solid, the Court affirmed. Balfour Beatty Rail v. Kansas City Southern Railway, No. 16-11645 (Feb. 15, 2018, unpublished).
