The Court of Appeals is expected to hear arguments in October in the two cases.
Baltimore County jury returned a $1.5 billion verdict against the oil giant. ExxonMobil appealed, and attorneys for residents asked the top court to bypass the intermediate appeals court. In March, in the second case, the state's second-highest court rejected much of a $147 million verdict, and both ExxonMobil and the residents appealed.
Attorneys for the residents as well as a spokeswoman for ExxonMobil said they were glad the top court agreed to take up the cases.
