What jurisdiction means
Jurisdiction is whether a court is allowed to hear your case at all.
It is decided before anybody considers the merits. A court can be convinced you are entirely right and still strike out the case because it had no authority to hear it.
That is why jurisdiction is usually the first thing a defendant's lawyer examines. Winning on jurisdiction avoids arguing about the facts at all.
How it is used
It works along several dimensions at once. Subject matter, meaning what kind of dispute it is. Territory, meaning where the parties and events are. And value, since some courts handle claims only up to certain amounts.
In Nigeria the practical questions are which court, in which state, and whether a specialised court has exclusive authority. Filing in the wrong one costs months and the filing fees.
Key features
- Determined before the merits of the case are considered
- Covers subject matter, territory and sometimes monetary value
- Cannot generally be created by agreement where a court lacks it by law
- Specialised courts have exclusive jurisdiction over defined subjects
- Contracts often include a jurisdiction clause choosing where disputes are heard
How this works in Nigeria
The National Industrial Court has exclusive jurisdiction over employment and labour disputes, which is why an employee suing over a dismissal goes there rather than to a State High Court.
The Federal High Court handles matters including company winding up, admiralty, taxation of companies, and disputes involving federal agencies. State High Courts have broad civil jurisdiction, including most contract and land matters within the state.
Magistrates courts handle lower value claims, with limits that vary by state. For a small debt, that limit is worth checking, because a Magistrates court claim is far faster and cheaper than a High Court action.
Jurisdiction vs venue vs governing law
Jurisdiction is whether a court has authority to hear the case.
Venue is which particular court location within a system will hear it, which matters mostly for convenience and cost.
Governing law is which country's or state's law applies to the substance of the dispute. These are separate choices, and a contract can be governed by Nigerian law while disputes are heard in arbitration seated elsewhere.
Commercial contracts usually address all three, and parties who read only the governing law clause sometimes discover they agreed to litigate somewhere inconvenient and expensive.
Limits and risks
Parties cannot give a court jurisdiction it does not have. An agreement that employment disputes will be heard by a State High Court does not override the National Industrial Court's exclusive authority.
A jurisdiction clause also does not help where the other side simply ignores it and sues elsewhere. You may have to appear in that court to challenge it, which costs money before the argument even begins.
Worth knowing
Read the jurisdiction clause before signing. A clause requiring disputes to be heard abroad can make a claim economically impossible for a small Nigerian supplier.
