If enterprises merge without authorisation, what would the Competition Authority do?

The Authority may give a direction to the company or companies involved – (a) not to complete or implement the merger; (b) to sell or dispose of in any other specified manner, any share, interest or other assets it has acquired pursuant to the merger; (c) to terminate any agreement, or provisions of an agreement, to which the merger was subject; and (d) to take such further measures as may be necessary to restore the conditions of competition existing prior to the merger.
