 An 1858 treaty extended navigation rights to Costa Rica, but Nicaragua denied passenger travel and fishing were part of the deal; the court ruled Costa Ricans on the river were not required to have Nicaraguan tourist cards or visas as Nicaragua argued, but, in a nod to the Nicaraguans, ruled that Costa Rican boats and passengers must stop at the first and last Nicaraguan port along their route.They must also have an identity document or passport.Nicaragua can also impose timetables on Costa Rican traffic.
