Core holding
Government must obtain warrant for CSLI — third-party doctrine does not apply
Duration threshold
>7 days of CSLI requires warrant per most 9th Cir. cases post-Carpenter
Retroactivity
US v. Diggs: Carpenter applies retroactively to pre-2018 CSLI collections
Suppression remedy
4 cases in 9th Cir. and Cal. address remedy — exclusion granted where warrant absent
Expert witness and science research
Research the scientific literature on forensic methods, eyewitness identification, drug testing procedures, and other evidence types your client faces. Find peer-reviewed critiques and expert qualification standards to challenge prosecution evidence.
Find peer-reviewed research on the error rates and reliability of hair microscopy comparison evidence. I need to challenge the prosecution's forensic hair analysis expert.
Found 31 studies. Key findings: FBI-commissioned review found hair microscopy has no validated scientific basis for positive identification — error rates undetermined. 2015 FBI acknowledgment letter cited in 3,000+ cases. FBI Microscopy Examiner Study (2012) found 12 of 13 examiner types made at least one error. References to Daubert challenges that succeeded on this basis in 5 jurisdictions.

Sentencing research and mitigation briefs
Research sentencing guidelines, departure standards, and comparable sentences for similar defendants. Build data-driven mitigation arguments supported by case law and social science research on recidivism, treatment, and rehabilitation.
Research downward variances granted for defendants with severe childhood trauma and PTSD in federal drug trafficking cases. What social science supports trauma-informed sentencing and which circuits have been most receptive?
Found 14 cases with granted downward variances citing childhood trauma and PTSD. Most receptive circuits: 1st, 2nd, and 9th. Key social science: ACE studies showing dose-response between adverse childhood experiences and substance use disorder (Felitti, JAMA 1998, 17,000 subjects). Recent: US v. Mosley (2nd Cir. 2023) held district court erred in not considering trauma history at sentencing.

Trial preparation and document review
Extract key facts from police reports, medical records, and investigation documents. Summarize lengthy discovery materials and flag inconsistencies across multiple statements and reports.
Summarize this 240-page police investigation file and flag any inconsistencies between the arresting officer's narrative, the civilian witness statements, and the incident report timeline.
Summarized 240 pages into key findings. Flagged 4 inconsistencies: Officer narrative places suspect at corner of 5th and Main at 10:42pm; witness A places him at 10:31pm one block south. Body cam log shows 11-minute gap between dispatch call and activation. Suspect's documented address differs from location of "routine patrol" claimed in report.

Frequently Asked Questions
Which courts does the Legal Research tool cover?
Case Law covers US federal courts (Supreme Court, all Circuit Courts of Appeals, district courts), state supreme courts and appellate courts across all 50 states, and select international jurisdictions. You can filter by jurisdiction, court level, and date range.
Can AI tools help me challenge forensic or scientific evidence?
Academic Research searches peer-reviewed literature on forensic science reliability, including studies critiquing hair microscopy, bite mark evidence, arson investigation methods, fingerprint analysis, and breathalyzer accuracy. Results can support Daubert/Frye motions and expert witness challenges.
How can AI support indigent defense with limited resources?
AI tools reduce research time significantly — what once took hours of Westlaw searching can be done in minutes. For public defenders carrying 100+ case dockets, AI lets you allocate more time to client contact and courtroom preparation rather than preliminary research.
Are AI-generated legal research results reliable enough to cite?
AI tools search real databases and return actual case citations, but you must verify every citation through Westlaw, Lexis, or court records before filing. Use AI to identify leads and surface relevant authority quickly, then verify and shepardize before relying on any case in a filing.
Can I use AI to find Brady material and officer misconduct?
News search and public records tools can surface news articles, civil lawsuits, and public disciplinary records involving law enforcement personnel. This can help identify leads for Brady disclosure requests, but always follow up with formal discovery demands and official personnel file requests.
