SLIDE 9 Mantovanelli v. France/principles:
[...] one of the elements of a fair hearing under Art. 6-1 is the right to adversarial proceedings;
- each party must in principle have the opportunity not only to make
known any evidence, but also to have knowledge of and comment on all evidence adduced with a view to influencing the court’s decision (Nideröst-Huber v. Switzerland, judgment 18/02/1997, § 24).
- where an expert has been appointed by a court, the parties must in all
instances be able to attend the interviews held by him or to be shown the documents he has taken into account.
- What is essential is that the parties should be able to
participate properly in the proceedings before the "tribunal"
(see, mutatis mutandis, the Kerojärvi v. Finland judgment of 19 July 1995, § 42).
[...] The Court has to ascertain whether the proceedings considered as a whole, including the way in which the evidence was taken, were fair under Art. 6-1 (see, mutatis mutandis, the Schenk v. Switzerland, judgment 12/07/88, § 46).
