This paper explains the existence of a particular formal model (drawn from Theoretical Astrophysics) whose thermodyna-mical phenomenology shows a possible second order phase transition (according to Landau's Thermodynamical Theory) that seems does not verify the (Birman-Goldrich-Jari¢) chain subduction criterion and the (Ascher's) maximality criterion of Landau's Phenomenological Theory. Therefore, it follows that Landau's Phenomenological Theory is more restrictive than the Landau's Thermodynamical Theory.
