Preliminary injunctions are rarely granted on an ex parte basis in Belgium and adversarial debates are considered a cornerstone of legal proceedings which can be deviated from only in cases of absolute necessity.

It remains to be seen how the law will be used and applied in practice, but it is an essential means in effectively appropriating, protecting and exploiting innovation by providing trade secret holders with the tools to protect valid trade secrets.
