A 2005 law capped noneconomic damages in such cases at $350,000. It was part of a broader effort to curb liability lawsuits. The Missouri Supreme Court ruled last summer that the cap is unconstitutional.
Missouri lawmakers are considering a measure that attempts to impose the limit on damages while avoiding the constitutional problem cited by the high court.
Senate debate about the legislation continued into the evening hours Tuesday. Earlier this year, House members voted to approve the measure.
Lawsuit limits is HB112.
