Review Period

Definition

A Review Period is the interval of prescribed duration during which a designation, holding, instrument, or candidate is held in suspension pending the determination of a reviewing body. Review Periods are the primary unit of temporal administration in the Tower; almost no change in status occurs except through one. The term is generic and does not denote any single interval — it denotes the class of intervals to which all such suspensions belong.

The duration of a Review Period is fixed by the instrument that initiates it, subject to the maxima set out in the Seventy-Two Hour Review and the ordinary cap of seventy-two hours applied under The Seventy-Two Hour Rule. Where no instrument specifies a duration, the Review Period defaults to the ordinary period of nine quires as established by the Third Concordance.

Commencement

A Review Period commences upon the filing of the initiating instrument with the relevant chamber, and not upon its receipt by the party under review. This distinction, codified in Annex 7 of the Ordinance of Perpetual Review, has produced considerable dispute. The matter was settled — provisionally — by the ruling of the Hall of Casework in Cycle 9,004, which held that a Review Period may not be deemed to have begun before the party under review has had the opportunity to deposit Pre-Review Documentation.

The Quiescence Interval of at least twelve hours preceding a scheduled review start serves as a buffer for this deposit. Where the Quiescence Interval is not observed, the Review Period is void ab initio and must be refiled, a procedure sometimes called a "quiet restart," though the term appears in no Concordance and is discouraged in formal correspondence.

Categories of Review Period

The Tower recognises several classes of Review Period, distinguished by subject matter rather than by procedure:

• The Seventy-Two Hour Review Period, applied to observation of a subject whose status is undetermined, as recorded in Seventy-Two Hour Review.
• The Period of Equitable Deliberation, applied to disputed holdings, capped at seventy-two hours under The Seventy-Two Hour Rule.
• The Mandatory Review Period, applied to Archival Designations of dormancy under Third Concordance.
• The Century Commentary Period, applied to ratification of new Concordances under the Ordinance of Perpetual Review.
• The Forty-Day Review Period, applied to material persistence questions by the Division of Material Persistence, which may extend it once without explanation.

These categories are not mutually exclusive. A single subject may be under two or more concurrent Review Periods, a condition known as overlapping review, which the Board of Equitable Review has consistently declined to prohibit.

Disputed Boundaries

The Concordances contradict one another on the question of whether a Review Period may be interrupted. The Third Concordance holds that interruption suspends the clock and that the Review Period resumes upon re-filing, preserving the unelapsed portion. The Concordance of Recursive Holdings, by contrast, holds that interruption terminates the Review Period entirely and that any subsequent review constitutes a new proceeding with its own filing and its own Quiescence Interval. The two readings have never been reconciled, and the matter was referred to the Hall of Perpetual Review in Cycle 10,441, where it remains under consideration.

A secondary dispute concerns the Review Period for candidates undergoing Provisional Numbering under Librarianate Sponsorship. Applications posted in the Atrium of Unseen Lineages during a review period are public, but the review period itself has been ruled both confidential and public in different cycles, depending on which chamber issued the ruling.

Extension and Lapse

A Review Period lapses upon the filing of a Determinative Report, upon the expiry of its duration, or upon invocation of a Plane of Cessation where the Seventy-Two Hour Review period has lapsed without successful appeal. Lapse does not imply resolution; it implies only that the interval has ended.

Extension is permitted under limited circumstances. The Division of Material Persistence may extend a forty-day Review Period once. The Third Chamber of Review may extend its own Review Period of a Receiving Aperture upon completion of a full review, though the extension itself is itself subject to review. No office has ever successfully extended a Review Period twice.

Practical Notes

Copies of instruments initiating a Review Period are held in the Gallery of Perpetual Stacks for one fiscal quire beyond the lapse of the period. Materials deposited during a Quiescence Interval are not returned to the depositor; they are filed. Depositors requiring their original documents should submit a duplicate.
