The Court-appointed expert must fulfil the task entrusted to him or her by following the perimeter of investigation indicated to him or her by the judge; sometimes the Court’s Expert takes investigative initiatives on his or her own that seem to exceed the perimeter; the advice is not always null and void if the principle of cross-examination between the parties is respected.
Ex officio technical advice is intended to help the judge in the evaluation of the elements acquired or in the solution of questions involving specific knowledge, it being understood that the party cannot invoke it to make up for its own evidentiary deficiencies.
