Abstract
In this note, an alleged lemma 3.6 stated in [2] is incorrect in general, by giving an example. In addition to this point, if the closure space studied in [2] was T1 space, then it is the discrete space (X, P(X)). As a consequence, Proposition 6.4, Corollary 6.4, Proposition 6.5, Corollary 6.6, Proposition 6.6 and Corollary 6.7 mentioned in [2] are trivially satisfied without proof.
