Abstract
Utilizing the notion of uniform equicontinuity for sequences of functions with the values in the space of measurable operators, we present a non-commutative version of the Banach Principle for L.

Key words: von Neumann algebra; measure topology; almost uniform convergence; uniform equicontinuity; Banach principle.
