    Summary: Let \(E\) be a Banach lattice and let \(M\) be a norm-closed and Dedekind \(\sigma\)-complete ideal of \(E\). If \(E\) contains a lattice-isometric copy of \(\ell_{\infty}\), then \(E/M\) contains such a copy as well, or \(M\) contains a lattice copy of \(\ell_{\infty}\). This is one of the consequences of more general results presented in this paper.
