The medical certificate is the foundation of an assault or hurt trial. It documents the injuries, their nature, probable cause, and the period over which they were caused, and the prosecution relies on it to connect the accused to the harm. The certificate must record the injuries as they were at the time of examination, since discrepancies between the description and the medical findings weaken the case.
The defence commonly attacks the medical evidence on three fronts: whether the injuries match the version in the FIR, whether independent medical opinion supports the classification, and whether the timeline of the alleged incident fits the medical findings. Where the certificate describes injuries inconsistent with the weapon or the story told, the court discounts the evidence accordingly. Re-examining the victim and obtaining a second medical opinion are legitimate steps where warranted.
For the defence, scrutinising the procedure is as important as challenging the doctor's skill. The examination must follow prescribed protocols, and the doctor must record the date, the nature, and the probable weapon. Any failure to follow procedure, such as examination long after the incident without explanation, is legitimate ground to question the value of the report. A meticulous reading of the certificate, not a bare denial, is what moves the court.
