traduction anglaise
Any person who, whether by profession or not, has special expertise in any matter, such as in science, art, craft, commerce, medicine, or foreign law, and whose opinion may be of use in deciding the case, may, in the investigation, preliminary hearing, or trial, be a witness on various matters, for example examining the body or mind of the injured person, the accused, or the defendant, examining handwriting, conducting experiments, or performing other tasks. An expert may render an opinion in writing, but must send a copy of that writing to the court and to the other party, and must appear to give evidence in support of it, unless there is a necessary cause or the parties do not wish to question the expert, in which case the court may admit the written opinion without the expert having to appear in support. Where the expert must appear to give evidence in support, a sufficient number of copies of the writing shall be submitted to the court not less than seven days in advance of the day of testimony, so that the other party may collect them. In giving evidence in support, the expert may read from the text he has written.

Annotation de l'entreprise
Section 243 opens Book 5, Chapter 5 on special experts and defines who may serve as an expert witness and how their opinions are received. Expertise may be professional or not, spanning science, art, craft, commerce, medicine, and foreign law, and typical tasks include physical or mental examinations, handwriting analysis, and experiments. The section allows a written expert opinion but, as a rule, the expert must appear to give supporting testimony (paragraph two) so the opinion can be tested by cross-examination; this may be dispensed with for necessary cause or where the parties do not wish to question the expert. A seven-day advance-copy requirement ensures fairness. The courts have accepted expert evidence such as aerial-photograph interpretation, and have held that failure of the examiner to testify may be cured where another witness confirms the examination and result.
Pourquoi cela est important en pratique
Expert evidence often decides technical criminal cases (forensics, medical causation, questioned documents). Remember the default: the expert should appear so you can cross-examine, and copies of the report must reach you at least seven days before testimony. If the other side tries to put in a bare written report, consider whether to insist the expert attend. Equally, weaknesses in an opposing expert's method are fertile ground for challenge. Instructing your own qualified expert early, with a lawyer, can be pivotal.

Supreme Court Judgment No. 5206/2559 (2016)
An expert, such as an aerial-photograph interpreter, is a recognised category of evidence under the Code, and where the expert testifies before the trial court in accordance with Section 243, and the scientific work was carried out to proper standards by qualified persons, the evidence is lawfully received.
An aerial-photograph interpreter testified about the interpretation of aerial photographs. The Supreme Court held she was an expert, a recognised type of evidence under the Code, whose testimony before the trial court complied with Section 243, and that the underlying scientific work (photography, survey, mapping) was done to proper academic standards by qualified persons, so the report and testimony were properly received.

Supreme Court Judgment No. 2234/2538 (1995)
Even if the prosecution does not call the examiner to testify in support of an expert examination report under Section 243 paragraph two, where the inquiry official testifies confirming the exhibit was sent for expert examination and found to be heroin, that evidence can establish the substance's identity.
The prosecution did not call the person who examined the exhibits to support the examination report under Section 243 paragraph two. The Supreme Court held that because the inquiry official testified confirming that the exhibits had been sent to an expert for examination and were found to be heroin, the prosecution's evidence could establish that the exhibits were heroin as charged.
