"The last council spent thousands of dollars on legal advice, to no avail," Mr Carter said.
"The law might be an idiot, but we have no choice but to obey it."
The saga began in 2003, when the Far North District Council applied to the Northland Regional Council for a reclamation consent to build the boardwalk, with a safety rail.
Some years before a hotel patron had fallen into the water and died, the coroner recommending that a railing be erected.
The consent was granted in 2003, the revised design submitted when that consent was appealed also including a railing.
The boardwalk was built in 2007/08, without a railing, although a temporary fence was erected in 2009 at the NRC's instruction. The Building Act also requires a safety railing where the drop is more than one metre.
The FNDC issued itself with a waiver in 2009, Mr Carter said, and removed the temporary fence, and had now reached the point where it was bound to comply with the consent and the Environment Court.
(Mr Carter did offer one glimmer of hope, however. He said the council would erect a barrier, perhaps in the form of a wire rope, and apply to the Environment Court for a waiver, in the hope of negating the issue of personal liability and saving ratepayers' money).
