Properly formulated questions should concern specialist knowledge: content, orientation, political context, signs of political campaigning, the meaning of symbols or the limits of competence of a previous report.
Questions of guilt, the elements of an offence or the lawfulness of actions generally fall to the court rather than the expert.
What you can do
- collect the disputed materials and their context;
- formulate appropriate questions for a specialist;
- assess whether a combined examination is needed;
- prepare a specialist opinion, including one based on review of an expert report.
