The circular nobody read still governs the room.

When a municipality publishes a new general valuation roll, it gives owners a period to inspect their values and object, and the notice announcing it is one of the least-read documents in any town.

It appears as a newspaper advert, a notice on the municipal website, perhaps a line on the rates account. Most owners are busy and assume it has nothing to do with them. But the value on that roll is the number the municipality uses to calculate property rates, and it usually stays in place until the next general valuation, years later. If the valuer has put a house well above what it would actually sell for, the owner pays rates on that inflated number every month until it is corrected.

Picture two owners on the same street whose values both jumped sharply. One read the notice, looked up the roll, gathered a few recent sales of comparable houses and lodged an objection within the period. The other found out when the higher rates appeared on the account, after the objection period had closed. The second owner is now arguing from behind, with less time and fewer easy options.

The notice was public all along. It governs what both of them pay, whether either of them read it or not.
