The Concurrent List comprises of the subjects which are of common concern both to the centre and the state governments. Ordinarily both the central and the state governments can frame laws on these subjects. However, if there is a conflict between the central law and the state law, over a subject in the Concurrent List, the central law would be effective. This List includes subjects like criminal and civil procedure, marriage and divorce, education, economic planning, trade unions etc. The Concurrent List has 47 subjects.
