Confirmed Threat

When NYPD officers swept Hamilton Hall on the night of April 30, 2024, Columbia University locked down the entire Morningside campus — and Columbia Law School's Jerome Greene Hall and the Arthur W. Diamond Law Library were closed alongside it. The law-school buildings remained closed for the better part of two weeks, then reopened with CUID-swipe-only access between 7 AM and 11 PM and restricted off-hours entry. The closure spanned final exams for the spring 2024 term and coincided with Columbia Law faculty publicly condemning the administration's response.

Shelter in place for your safety due to heightened activity on the Morningside campus. Non-compliance may result in disciplinary action. Avoid the area until further notice.
Verbatim text of the campus-wide Columbia emergency text/email alert at 8:16 PM EDT on April 30, 2024 — the same alert documented in the Hamilton Hall takeover case (2024-04-30-columbia-university-hamilton-hall-takeover) and included here because it applied to Columbia Law's Jerome Greene Hall as part of the Morningside footprint
The 'Non-compliance may result in disciplinary action' clause — conditioning the shelter-in-place on disciplinary risk rather than physical danger — drew significant subsequent criticism from faculty and student commentators
This alert applied to the entire Morningside campus including Columbia Law's Jerome Greene Hall — the law school did not receive a separate notification

Dear Members of the Columbia Law School Community: Jerome Greene Hall, the Arthur W. Diamond Law Library, and Greene Annex will remain closed today and until further notice. CUID is currently required to enter the Morningside campus at the 116th Street and Broadway gate. Faculty are working with the Office of the Dean of Students to accommodate exam-period needs remotely. Please do not attempt to come to campus unless instructed.

Jerome Greene Hall and the Arthur W. Diamond Law Library will reopen with CUID-swipe access between 7 a.m. and 11 p.m. Security officers will be stationed at the entrance. Access is limited to Columbia Law School students, faculty, and staff. The law library is open to the law school community only during this period; visiting researchers and unaffiliated patrons may request access through the Reference Office.

Reconstructed from the CLS building-access page, which documents the restricted-access posture that emerged from the April-May 2024 lockdown and persisted as the school's new baseline
The 7 AM to 11 PM CUID-swipe window represents the new normal at Columbia Law and is itself a notable institutional outcome of the spring 2024 protests
Context

Background

On the night of April 30, 2024, NYPD swept Columbia's Hamilton Hall after pro-Palestine protesters occupied the building during a campus-wide encampment. Columbia locked down the entire Morningside campus, restricting access to the 116th Street gate with CUID-only entry. While the main public attention focused on Hamilton Hall (covered in a separate case in this archive), Columbia Law School's principal classroom and library buildings — Jerome Greene Hall, the Arthur W. Diamond Law Library, and Greene Annex — were closed alongside the rest of the campus during the lockdown. The closure spanned the spring 2024 final-exam period, forcing Columbia Law to revise exam policies and accommodate students remotely. 54 Columbia Law faculty publicly condemned the administration's response to the broader protests. When the law-school buildings reopened in mid-May, they did so with CUID-swipe access from 7 AM to 11 PM and restricted off-hours entry — a new baseline that has persisted. The case is included in the archive because professional-school students at a separately housed school can be swept into a main-campus emergency-notification footprint and have to navigate building closures, exam adjustments, and faculty divisions that are specific to the school. Columbia Law's institutional alerts during this period — the Morningside SMS, the dean-of-students emails, and the building-access page revisions — collectively functioned as a sustained 'alert sequence' rather than a single notification.
Analysis

Key Findings

Jerome Greene Hall and the Diamond Law Library were closed for nearly two weeks during the spring 2024 final-exam period — one of the longest non-weather closures in Columbia Law School's history
54 Columbia Law faculty publicly condemned the administration's response in a faculty letter, an unusually public faculty break with administration
The post-lockdown CUID-swipe access policy (7 AM to 11 PM) became the school's new baseline rather than a temporary measure
Illustrates the 'sweep-in' problem for professional schools: when the parent university locks down, professional-school students with separate buildings still operate inside the same emergency-notification perimeter
Outcome
Jerome Greene Hall and the Diamond Law Library reopened with restricted CUID-swipe access by mid-May 2024. Final-exam policies were temporarily revised to accommodate the building closure. 54 Columbia Law faculty issued [a letter condemning the administration's response](https://theintercept.com/2024/04/22/gaza-protests-arrests-columbia-law-school/) to the broader Morningside protests. Columbia's Hamilton Hall takeover and the resulting lockdown is treated separately in the archive; this case focuses on the law-school-specific consequences.
