Case law for patrol

Delaware decisions and the U.S. Supreme Court cases that decide your stops, in plain English with the citation.

Federal floor, Delaware rules

U.S. Supreme Court decisions set the minimum for every stop, search and arrest. Delaware’s legislature and courts can add stricter rules, and the answer on the street depends on both. The Delaware pack keeps the state’s own statutes and decisions next to the federal cases, and our blog breaks down both, state by state.

Delaware decisions officers should know

Delaware Supreme Court · 2001

Caldwell v. State

A traffic stop must stay tied to its purpose. Frisking and handcuffing a driver stopped for a parking violation, based only on nervousness, an arm movement, and not knowing his passenger's name, turned the stop into a new detention with no independent justification. With no facts suggesting he was armed and dangerous, the drugs found were suppressed.

Delaware Supreme Court · 1983

State v. Cooley

The collective-knowledge / fellow-officer rule applies only where officers actually communicate the facts establishing probable cause; probable cause cannot be imputed to an arresting officer absent such communication.

457 A.2d 352

Find the opinion for State v. Cooley

Delaware Supreme Court · 2011

Lefebvre v. State

DUI probable cause is assessed on the totality of the circumstances, and probable cause that exists before field sobriety testing is not negated by the driver's successful performance on those tests.

19 A.3d 287

Each summary was checked against the court’s majority opinion on September 30, 2026. Read the decision and follow your agency’s policy; this is reference guidance, not legal advice.
