As a solution to face the phenomenon of Constitutionalisation of Private Law, the author proposes to understand Commercial Law as a Constitutional Fragment, according to the concept used by Gunther Teubner.  This proposal is the result of studies about the juridical protection of the environment in Colombian Commercial Law.

The conclusion of the article is that, due to the difficulties to combine the different discourses of Commercial Law and Environmental Law, it is necessary to rethink the contents of Commercial Law from inside, in order to realize the idea of unitas multiplex or unity in diversity and diversity in unity in the Law discourse.
