Texaco Inc. asked for a retrial in the Pennzoil case.

Texaco told the 1st Texas Court of Appeals that Pennzoil Co. improperly responded to the court's recent ruling in the landmark case. Last month, the appeals court upheld a verdict that Texaco wrongfully interfered with Pennzoil's planned merger with Getty Oil Co. The court also upheld an award of $7.53 billion in actual damages, but reduced punitive damages to $1 billion from $3 billion. Texaco says that under Texas court rules, it is entitled to a new trial because Pennzoil failed to agree to the revised award.
