Case Law in HeinOnline

HeinOnline has extensive case law coverage, much of which is provided through a partnership with Fastcase. The U.S. Reports, which contain the officially-published opinions of the U.S. Supreme Court, are available from inception to current in HeinOnline’s U.S. Supreme Court Library.

The partnership HeinOnline has with Fastcase provides access to case law from additional courts, including:

  • Federal circuit courts
  • Federal district courts
  • State appellate courts
  • Many more!

Coverage of case law powered by Fastcase dates back, in most cases, to the 1950s or even earlier. For HeinOnline users, this partnership offers a comprehensive and incredibly affordable research experience without the hassle of using multiple databases.

Finding Cases in HeinOnline

HeinOnline’s platform is easy to use, and there are multiple ways to quickly find a case by citation, case title, or topic.

Citation: Using the one-box search top of any page in HeinOnline, enter a case citation and use the Citation option from the drop-down menu.

If a case is only available via Fastcase, it will automatically be imported into the HeinOnline interface. If a case is available in HeinOnline’s U.S. Reports and via Fastcase, users are able to select their preferred version.

Additionally, citations on pages throughout HeinOnline are highlighted in blue. Clicking these citations will retrieve the document associated with the cite, whether it’s a case, article, or external website.

Case Name: For U.S. Supreme Court cases, enter the U.S. Supreme Court Library. Click the Advanced Search link located beneath the main search bar at the top of the page. Use the case name field to enter the terms.

To find cases available only via Fastcase, select Fastcase* from the list of subscribed databases on the HeinOnline Welcome Page. Enter the terms in the Case Name field.

Topic: To search only Supreme Court cases by topic, enter the U.S. Supreme Court Library. Use the one-box search bar located at the top of the page, or use the Advanced Search link to search within specific fields. For example, enter “illegal search and seizure” in the one-box search bar and select the Just Search for option:

To search across Fastcase content, select Fastcase* from the list of databases on the HeinOnline Welcome Page. Enter your terms into the text field.

Case results will also appear when searching across all subscribed content.*

If searching from the HeinOnline Welcome Page, you can limit results to include only cases using the Section Type facet.


ScholarCheck and Bad Law Bot: Two Powerful Tools

Hein’s ScholarCheck tool is integrated with all case law, whether it’s native to HeinOnline or Fastcase. ScholarCheck enables users to link among related documents and to view articles and cases* which cite other articles and cases. It also counts the number of times articles and U.S. Supreme Court cases are accessed by other HeinOnline users within a rolling 12-month period. Look for ScholarCheck information in search results or within documents. Cited-by information for articles and cases are hyperlinks which link to the list of articles and cases* citing each document.


Fastcase’s Bad Law Bot helps researchers determine when negative treatment is posted to a case. Look for red flags in search results and within Fastcase documents; this flag is an indicator that the case has potentially been overturned or overruled by a subsequent case. Link* to the list of cases which have posted negative treatment to a current case.
