unjustifiable
Cannot be excused
Unjustifiable describes something that cannot be defended or excused by any reasonable standard.
An unjustifiable expense has no legitimate purpose.
Unjustifiable force exceeds what circumstances warrant.
The word carries moral weight—calling something unjustifiable is stronger than calling it wrong, suggesting no argument could make it acceptable: The delay was unjustifiable given the urgency.
