Mitigation

Evidence introduced at a criminal trial, usually by a defendant, to reduce the seriousness of the alleged crime, or to support the otherwise good character of the defendant, so that the crime may be less harshly punished. Also, mitigating circumstances, are such as do not constitute a justification or excuse for the offence committed, but which, in fairness and mercy, may be considered as extenuating or reducing the degree of moral culpability.
