In this paper, we study a non-Riemannian quantity \({\bar{{\bf E}}}\)-curvature. We prove that if F is a projectively flat Finsler metric of nonzero flag curvature, then it is Riemannian if and only if \({{\bar{\bf E}}}\)-curvature vanishes. Further, we characterize the Einstein-Douglas metrics with vanishing \({{\bar{\bf E}}}\)-curvature.
