Fully disjunctive reasoning would require that an evaluation of the term 'married' and its negation take place.
Hint: Human logical reasoning is based on time and space. Counter-measures can involve manipulations of time and space. In this instance, there is a rather lengthy history of voiding or invalidating the state of marriage which can extend forward and backwards in time. A good lawyer or cleric should be familiar with this.
It is a dangerous weakness of ours.
