Cross-Sector Dispensation

A Cross-Sector Dispensation is a written instrument by which an operation properly subject to the procedure of one sector is transferred, for a fixed term, to the procedure of another. The instrument does not move the operation, the personnel, or the floor; it moves only the rules that apply. A lift maintenance party working ninety metres inside the Stones sector may thus be governed, on paper, by the much older stair protocol of Sector Theta, provided a Cross-Sector Dispensation has been sealed and entered in the Reference Cross-Index before the work begins.

The practice is attested from at least Tower Year 5461, though the earliest forms were informal notes passed between floor clerks and were not recognized by the Librarians as a distinct instrument until the recensions of the Fourth Concordance. Cross-Sector Dispensations are frequently confused with the Regulatory Waivers, which excuse an operation from a rule; a Cross-Sector Dispensation excuses nothing and instead substitutes a different rule, usually a stricter one, on the reasoning that sectors enforce their procedures more conscientiously on borrowed business than on their own.

Form and sealing

The instrument runs to a single folded leaf, bearing on its face the originating sector, the receiving sector, the operation described in not fewer than four lines, and a terminal date. On its reverse it bears the seals of both sector registries and, where the receiving sector maintains a shaft, the countersignature of the shaft warden. The term may not exceed eleven months; dispensations of longer draft are returned unsealed, a formality that accounts for a noticeable share of the correspondence arriving at Floor 7,301.

Sealing requires the physical presence of both registrars or their duly appointed seconds. Registrars are not permitted to seal their own sectors' dispensations, nor to seal more than three in a single day, nor to seal any instrument on which their own name appears as the subject of the operation. The last prohibition was added after the affair of Registrar Ovell, who in the winter of 5488 granted himself a dispensation permitting the use of a receiving sector's stationery allowance, and was found to have done so three hundred and forty times.

Senn and the doctrine of refusal

A Cross-Sector Dispensation does not escape the Senn Dispensation. The Director retains the right to refuse one operation in four without giving reasons, and the refusal need not distinguish between operations that cross sectors and operations that do not. Practitioners have long argued that a refused cross-sector operation is doubly disadvantaged, having lost both its own procedure and its access to the receiving sector's, and this argument has been made in writing at least nine times without altering the arithmetic.

The Fifth Concordance is generally cited for the proposition that a dispensation may not be used to circumvent a warranted floor. Annex 4 of the Fifth reads: "No instrument of transfer shall open, unseal, or render procedurally available any floor whose warrant has not been read." The Spiral Sector's four warranted floors have accordingly never been made available by dispensation, though three separate attempts were made between 5510 and 5532 and all three remain in the archive as examples.

Use in the Humming Sector

The 900-floor administrative bloc of the Humming Sector issues more Cross-Sector Dispensations than any other jurisdiction in the Tower, chiefly because its internal procedures are keyed to the acoustic tolerances of Central Spire of the Humming Sector and cannot be applied elsewhere without amendment. Work on Floor 317, which falls within the bloc, is almost always dispatched under a standing dispensation to Sector Theta's older and quieter provisions.

"Where a procedure cannot travel, the operation shall travel instead, or failing that shall be recorded as having intended to."

— Third Concordance, Annex 2, clause 9

No operation has ever been recorded as having intended to travel, a circumstance the cross-referential offices have chosen not to examine.

Dispute: origin and authority

There is no settled account of which Concordance authorizes the instrument. The Second Concordance states plainly that "sectoral procedure is not transferable" (Annex 7, clause 3), and this sentence has never been repealed. The Seventh Concordance asserts the opposite in a single line — "and yet it is transferred daily" — without further argument or citation. The Ninth Concordance resolves the matter by declaring both prior statements to be descriptive rather than prescriptive, which satisfies few and is nonetheless the position of record.

A minority reading, advanced by Archivist-Proctor Archivist-Proctor Linus and never formally withdrawn, holds that the Second's prohibition applied only to the Cross-Referential Audit then in progress in Sector Theta, and that its survival as general law is the result of a copying error in the 5479 recension.

Record-keeping and loss

All sealed dispensations are entered in the Reference Cross-Index under the receiving sector, not the originating one, a filing rule that has caused the loss of an estimated one thousand instruments and at least two operations. Archivist-Proctor Linus has petitioned for reversal of the rule in every year since 5490. The petition is refused on the grounds that reversal would require re-indexing.

Where a dispensation's terminal date passes before the operation concludes, the operation reverts at midnight to its originating sector's procedure and must be re-declared in writing by the second bell. Parties caught between procedures during the changeover are advised to stand still and keep their hands visible.
