This contribution is the formalisation of a paper that appeared in Proc. of ICALP 2005: "Up-to Techniques for Weak Bisimulation". First we define a framework for defining up-to techniques for weak bisimulation in a modular way. Then we prove the correctness of some new up-to techniques, based on termination guarantees. Notably, a generalisation of Newman's Lemma to commutation results is established.
