Let M be a riemannian manifold with a riemannian foliation F. Among other things we construct a special metric on the graph of the foliation,\(\mathfrak{G}(F)\), (which is complete, when M is complete), and use the relations of Gray [1] and O'Neill [7] and the elementary structural properties of\(\mathfrak{G}(F)\), to find a necessary and sufficient condition that\(\mathfrak{G}(F)\) also have non-positive sectional curvature, when M does.

This condition depends only on the second fundamental form and the holonomy of the leaves.

As a corollary we obtain a generalization of the Cartan-Hadamard Theorem.
