psychiatric visum et repertum, or being an expert witness in the court of justice.

Research location is in Yogyakarta and the research subject is Yogyakarta
District Court. Data collection was done by interviews and literature study.
Research data was analysed by decriptive method, that is, data collected from the
primary and secondary data which is systematically and logically written
according to the deductive pattern, and then explained, written, and integrated
based on scientific normative system.
Research result gives conclusion and discussion which explained that
psychiatrist’s official statement will determine whether defendant who is being

official statement has a verification power which is similar to the other evidence,
but the judiciary unnecessarily affected by the expert’s official statement, and the
necessity of psychiatrist’s official statement in the inland areas is difficult,
because of the difficulty to get the psychiatrist there of the limited transportation,
and the payment which is given by the government is not adequate, so an
additional budget will be needed.
