Abstract: This paper presents a necessary and sufficient condition on the convex function $f$ in order that continuous solutions to

\begin{displaymath}\hbox {minimize} \int _{\Omega } f(\Vert\nabla u(x)\Vert) \, dx \hbox { on } u^{0} + W^{1,1}_{0}(\Omega )\end{displaymath}

satisfy a Strong Maximum Principle on any open connected $\Omega $.
