HARICA votes "yes" to ballot SC46.

FWIW, we've had slight discrepancies in our processes in the past and we 
managed to overcome without too much additional administrative overhead. 
I believe we can overcome the effective date problem with a cleanup 
ballot following this ballot. With that said. I don't see violating any 
Bylaws or Charter rules on having an effective date on a requirement 
which pre-dates the completion of the IPR period.
