[The sick accused: forensic and emergency aspects in the courtroom].

Evaluation of the fitness of an accused person to participate in legal proceedings is a classic forensic activity. Before the trial, the forensic expert will already assess any preexisting somatic and psychological illnesses and give a written expert opinion describing the condition of the accused at the time of the examination and assessing whether he is fit to stand trial. Nevertheless, decompensation or aggravation of a disease may occur--especially in stress situations as they are to be expected for an accused in the courtroom--so that apart from the current evaluation of the state of health of the accused, emergency treatment may occasionally become necessary in the courtroom. The article tries to answer the question how the expert can meet this challenge.
