Medical evidence refers to all statements and documents presented in court related to medical matters. There are two main types: oral and documentary. Documentary evidence includes medical certificates, medico-legal reports, and dying declarations. Oral evidence allows for cross-examination of witnesses. Documentary evidence is only accepted based on supporting oral testimony. Medical certificates document illness, death, and other health matters but must be issued by a qualified practitioner. Medico-legal reports examine victims of crimes like assault and contain observations and opinions. Dying declarations are statements from those dying unlawfully about the cause of death.
