review text: The completeness of the root system of a boundary value problem for first-order systems of ordinary differential equations is under investigation. The concept of weakly regular boundary conditions is introduced by the authors and taken into account for the main result's proof. Necessary and sufficient conditions for completeness of the root system are given.
