If upon receiving the objections, or after the hearing, the commissioner finds any part of the special purpose apportionment against the objecting company excessive, erroneous, unlawful or invalid, he shall transmit to the objector, by registered mail, his findings and an amended statement of special purpose apportionment in accordance with those findings, which shall have the same force and effect as an original statement of special purpose apportionment. If the commissioner finds the entire statement of special purpose apportionment unlawful or invalid, he shall notify the objector, by registered mail, of that determination, and the original statement of special purpose apportionment shall be null and void. If the commissioner finds that the statement as rendered is neither excessive, erroneous, unlawful or invalid, in whole or in part, he shall transmit notice thereof to the objector by registered mail.
