Can a court and tribunal be seized of the same subject matter?

Yes, a court and a tribunal can be seized of the same subject matter, depending on the legal framework and jurisdiction. This situation often arises in cases where both administrative and judicial remedies are available, allowing parties to seek resolution through different avenues simultaneously. However, the outcomes may differ based on the authority, rules, and procedures governing each body. It is essential to consider the specific laws that apply to the case to determine the implications of pursuing both routes.
