Abstract: We characterize the curves in ${\mathbf{P}}^{3}$ that are minimal in their biliaison class. Such curves are exactly the curves that do not admit an elementary descending biliaison. As a consequence we have that every curve in ${\mathbf{P}}^{3}$ can be obtained from a minimal one by means of a finite sequence of ascending elementary biliaisons.
