Determining identical causes of action
In Yap v. Chua,[1] the Supreme Court held that the test to determine
whether causes of action are identical is to
ascertain whether the same evidence would support both actions, or whether
there is an identity in the facts essential to the maintenance of the two
actions. If the same facts or evidence would support both actions, then they are
considered the same; a judgment in the first case would be a bar to the
subsequent action.
