US federal litigation, tracked as it forms.

Repleader is a free public record of new filings, rulings and enforcement actions in mass tort, product liability, class action, securities, antitrust and consumer cases. Related cases are grouped into matters, scored for momentum, and published with a link to the source for every fact.

What inertia means

Inertia is a score from 0 to 100 for how much a case, or a group of related cases, is moving right now. It rises with new filings, rulings, courts, plaintiff firms, steps toward an MDL and linked agency actions, and it fades when the dockets go quiet.

The score is computed by Repleader, so it is always labeled modeled. Read the inertia method.

How sourcing works

• Court records come from Free Law Project CourtListener, an open archive of federal dockets and opinions.
• Enforcement actions come from federal agency releases, which are public domain, and from state attorney general announcements, which we cover with the headline, our own short summary and a link.
• News coverage appears as a headline, publisher, date and link. We do not copy articles.
• Every fact on a page links to the record it came from. Numbers we compute are labeled modeled and link to the method.
• Allegations are reported as allegations and attributed to the filing that makes them.

The full rules are in our principles and methodology.

Where things stand

Repleader is in its first build. Matter, case and court pages will appear here as they pass our publishing checks. Until then the site carries its rules, its method and a way to ask for coverage.
