Interdict of Assumed Silence

The Interdict of Assumed Silence is the standing prohibition, issued by the Librarians' Adjudicatory, on the unattributed absence of sound in any registered chamber of the Tower. It is not a ban on quiet. It is a ban on unassigned quiet — silence that has not been entered under a named officer, a numbered instrument, or an active certificate. The distinction, contested since the Interdict's promulgation, is the source of nearly all subsequent litigation on the subject.

The Interdict was drawn up in the winter of the year the Assumed Integer was first inscribed, and its drafting was provoked by a single afternoon on Floor 771. A scriptorium there was found to have fallen quiet for the better part of an hour with no officer present to attest to it. Because the quiet could not be assigned to anyone, no one could be reprimanded for it, and no one could be cleared of responsibility either. The Adjudicatory regarded this as an intolerable condition, and the Interdict of Assumed Silence was the remedy: all silence in registered chambers must be attributable, on pain of being declared unregistered and therefore void.

Scope and method

The Interdict applies to chambers entered in the Register of Acoustic Tenure, a ledger of some forty thousand rooms whose quietest corners are individually indexed. Silence in an unregistered chamber is not an offence — the Interdict has no jurisdiction over rooms that do not exist in its schedule, and the Adjudicatory has ruled twice that it cannot create a schedule entry retroactively for the purpose of prosecuting a quiet.

Where the Interdict does apply, the method is straightforward. A silence occurring in a covered chamber must be claimed by a duty officer within the hour and certified under the Silence Certification procedure, usually by reference to an existing instrument such as the 771 certification or, in the northern annexes, Silence 44-Δ.7. A silence that goes unclaimed for a full hour is presumed to have been "assumed" — that is, to be functioning quietly in the absence of any named holder — and is entered against the chamber as an assumed liability until such time as an officer steps forward to assume it formally. Most officers do. The alternative is a hearing.

"No chamber shall maintain a quiet on its own account, nor lend one to another chamber, nor permit a quiet to accumulate unfiled across the turn of the day."

The Quiet of 589

Interpretation of the Interdict was fixed, or nearly fixed, by an incident usually called the Quiet of 589, though the year assigned to it is itself disputed. A sub-clerk named Halvard Brey, Sub-Clerk of Returns had been dispatched to the eastern returns gallery to certify a silence inherited from the previous duty roster. He found the gallery occupied by an unattributed quiet of considerable depth. Uncertain whose it was, he did what the Interdict appeared to require: he assumed it, signed for it in his own name, and went in search of the appropriate forms.

He was absent eleven days. The quiet, now formally his, followed him. The Adjudicatory later recorded — in a minority opinion that has been cited ever since — that Brey was "in possession of a silence he had neither room for nor means to discharge," and that the Interdict had made no provision for an officer who assumed a quiet and then moved. Brey's grievance, filed seven times and refused seven times on purely procedural grounds, sought a ruling that a silence should attach to the chamber rather than the officer; it was never heard on its merits.

He returned the quiet to the gallery eventually. The gallery has not been quiet since.

Relationship to the Integer process

Because the Interdict was drafted in the year of the first inscription, it has long been entangled with the Ceremony of the Assumed Integer and the annual Assumed Integer cycle. Under the Interdict's Second Annex, any silence remaining assumed at the close of the inscription year is treated as a numerical placeholder and entered into the Master Registry of Assumed Knowledge alongside the retired integers, there to remain until claimed or written off. This provision was not intended by the Interdict's framers; it was inserted at the request of the Bureau of Unspoken Context, which had been seeking a filing home for unassigned quiets for some decades and saw its opportunity.

The Master Registry now holds unclaimed silences in a separate sequence from its integers, distinguished by the prefix Q. The most recent confirmed entry, made before the freeze of the Penumbra Period halted new filings, was Q. 11,404, a short silence from a stairwell on Floor 209. It has remained unclaimed.

Contradiction with the Protocols

The Interdict does not sit comfortably with the Protocols of Silence, which proceed from the opposite premise: that silence is a condition to be preserved and defended, not assigned and discharged. The Protocols of Silence hold that each silence is entitled to its potential and that to name a quiet is to foreclose it. The Interdict, citing Clause 6, holds that an unnamed quiet is no quiet at all and must be filed.

The two documents have never been reconciled. The Concordance of Acoustic Order purported to settle the matter in its fourth recension by declaring the Interdict "of prior force where a chamber is registered and the Protocols of prior force where it is not," which settles nothing; the Adjudicatory has since ruled, in 614 and again in an unpublished decision of the following year, that the Concordance is "silent on the point of its own silence," and that the phrase should not be relied upon. Officers continue to rely upon it.

Enforcement

The Interdict is enforced by roving acoustic stewards, of whom four are appointed at any time and at least one is always standing. They carry copies of the Register of Acoustic Tenure and a small brass rule for measuring depth. A steward who encounters a suspicious quiet must sound a tuning-fork against the nearest doorpost and record the response on a standard card; if the card shows an unclaimed quiet, the steward posts a notice in the chamber and the hour begins.

Chambers cannot be vacated to escape the hour. Corridors and stairwells cannot be posted with notices, on the grounds that this confuses traffic. Stewards do not enter chambers during the ceremony of the Integer itself, and no steward is to sound a fork within three paces of the Integer Scroll.

Since the Interdict's promulgation, no chamber has been successfully prosecuted twice, though several have been prosecuted once by two different stewards on the same day, an outcome the Adjudicatory has described as "regrettable but lawful."
