invalidity
State of unsoundness
Invalidity is the state of being invalid—lacking legal force, logical soundness, or factual basis.
A contract may be challenged on grounds of invalidity; an argument's invalidity means its conclusion doesn't follow from its premises.
In British usage, invalidity also refers to the condition of being an invalid—chronically ill or disabled: invalidity benefit, invalidity pension.
