Grievous harm is defined by criteria set in Government Resolution No. 522 of 2007 and the Ministry of Health rules made under it: harm dangerous to life at the moment it was caused, or resulting in loss of sight, speech, hearing or an organ, disfigurement of the face, significant permanent loss of general capacity for work of at least one third, or termination of pregnancy.
Whether an injury meets that definition is decided by a forensic medical examination, and that examination decides which article applies. Harm of medium gravity falls under Article 112 with far lower sentences. So the forensic report is not background material in these cases — it is the case, and it is examinable: whether the criteria were applied correctly, whether pre-existing conditions or the quality of the medical treatment contributed, and whether the causal link between the act and the outcome is actually established.
