Since the WHLFBC contains information about the hospital and the attending physician (items which also were verified as 'matching' the original birth certificate on file) the presumption is clearly that the birth information came from the hospital.
When people get copies of their b.c.'s, there is nothing ever indicating who initially submitted the information to the vital records office. That the record exists and is maintained as part of the vital records system suffices to establish its bona fides.
That's how vital records work.
The attending physician was not verified as "matching"
Say Crook, how Hawaiian "vital records" really work is that they would or still do, take any "witness(es)" - LoL - "secure" from sourc(es), about a Hawaiian birth to produce record(s) or amendment(s) at anytime for their so-called vital records.
