Data suitable for proving the facts of the dispute such as written or published texts, deeds, drawings, plans, outlines, photographs, films, visual or audio recordings as well as data stored in electronic media and similar data storage devices shall be considered as documents within the scope of the CoCP (art. 199). This is a very inclusive definition. The wording of the provision is not restrictive; therefore, any kind of device that can somehow store data and is suitable for proving a fact is a document.

However, expert reports are discretionary evidence written by experts and is a separate type of evidence.
