The latest lawsuit stemming from a Virginia-based energy company’s $268 million acquisition of two coal mines from Cliffs Natural Resources Inc. has landed in Delaware’s Chancery Court, with the buyer alleging fraud and breach of contract in a 19-count complaint.

Seneca Coal Resources this week accused Cliffs and its brass of concealing a range of liabilities associated with the two West Virginia mines as it exited the coal business, saying that it would not have accepted the terms of the 2015 deal had it known about millions of dollars in obligations in legal exposure the company had unwittingly assumed in the transaction.
