MEMO · 4TH AMEND · SUPPRESSION
GROUND-TRUTH VERIFIED
Your issueCan I suppress cell-site location data the State obtained without a warrant?
Likely yes. Warrantless acquisition of historical cell-site location information is a Fourth Amendment search requiring a warrant supported by probable cause Carpenter v. United States, 138 S. Ct. 2206 (2018). The government cannot rely on the third-party doctrine to bypass this, given the "detailed, encyclopedic" record of movement the data reveals id. at 2217.
Frame the motion around the reasonable-expectation-of-privacy test Katz v. United States, 389 U.S. 347 (1967), anchored to U.S. Const. amend. IV. Absent a recognized exception, suppression is the remedy.

The line we do not cross
An AI that invents a case can end your career.
In 2023, a lawyer was sanctioned after filing a brief with six court decisions that did not exist — fabricated by a general-purpose chatbot. Quarro is built so that cannot happen: it can only cite law that is actually in the record, and it shows you the source for every line before you file.

Mapped to Your Matter
Your issue, jurisdiction, and posture become the query. You get a memo, not a pile of links.
Synthesis · your case
From question to argument
Three steps to hearing-ready.
Step one
State the matter
Describe your issue the way you'd tell a colleague — jurisdiction, facts, where you are in the case. No boolean, no query syntax.
Step two
Quarro reads the record
Our model searches only verified primary law and the case record for your jurisdiction — retrieval grounded in real documents, never in memory.
Step three
Get a cited memo
An argument-ready research memo: the answer, the authorities, the counter-arguments, and a citation you can pull for every claim before you file.
Privileged & confidential
Your matters are protected the way your ethics rules require.
In plain terms — no jargon. If it wouldn't satisfy your duty of confidentiality, we wouldn't build it.
🔒
Your case never trains our model.
What you research stays yours. We never use a client's matter to teach the system or improve it for anyone else.
Per-firm isolation · no cross-tenant learning
✎
Every answer comes with receipts.
Nothing is asserted without a source you can open and read. You verify the law yourself before it goes in a filing.
