La fusion de sociétés en droit interne et international : contribution à la notion de « contrat-organisation »

The merger is an operation whereby one or several companies transfer all their assets, after their dissolution without going into liquidation, to an existing or new company in exchange for the issue of shares to their shareholders. This definition adopted by European and French legislators brings out the merger's main effects without revealing its legal nature. Both doctrine and jurisprudence have struggled to clear up the confusion. The concept of contrat-organisation seams to be the most suitable in order to seize properly the merger's legal nature.

The merger is a contrat-organisation that leads to join the merging companies' assets and members in an existing or new company. Therefore, the operation cannot be reduced to a simple exchange of assets and values between parties. On the contrary, the gathering of the contracting companies in a single entity will establish a rule of cooperation between them in a way that they will make profits or loose jointly. The transposition of the same legal characterization in the private international law requires a distributive application of the lex contractus and the lex societatis to be able to choose the applicable law to the merger. Applying the merger's own specific lex contractus will help address the insufficiencies of the classical conflict of laws' method solely based on the division of laws applicable to the merging companies.
