B. Notwithstanding any provision of law to the contrary, the residency requirement set out herein shall not apply to any judge whose residence prior to July 1, 1977, is outside the boundaries of a new district created by § 16.1-69.6, if such judge is a resident in the geographical area which encompassed the prior district.
