Abstract We prove that a bounded poset of finite length is a lattice if and only if the following condition holds: whenever two elementsx 1,x 2 that cover a common elementx are both smaller that two elementsy 1,y 2 that are covered by a common elementy, then there exists an elementz that is an upper bound forx 1,x 2 and a lower bound fory 1,y 2.
