Class actions and group litigation.
Collective proceedings, GLOs, and mass claims where common issues must be proven across a complex and varied record.
Group and collective litigation multiplies every challenge of a complex case. Teams must prove common issues from the defendant's record while understanding, categorizing, and evidencing the individual circumstances of thousands of claimants. Certification, sampling, and distribution add procedural layers that depend on a rigorous command of the facts.
Crimson builds a Case Model that maps the common issues to the defendant's document production and the lead or representative claimant evidence, while keeping the structure of the class or group in view. Teams can establish the merits with confidence, manage the evidence across cohorts, and prepare certification, trial, and settlement work with every assertion cited to its source.
Typical case file
- Defendant document productions and internal records
- Claimant questionnaires and witness statements
- Expert reports on liability, causation, and damages
- Certification and GLO applications
- Regulator findings and decisions
- Product, service, or policy documentation
- Marketing and customer communications
- Court and tribunal orders
The pressures
facing your team.
Common issues across varied facts
Teams must prove the case at a class-wide level while staying accurate to the individual claimants' circumstances. Both require deep command of the record.
Asymmetric discovery
The defendant holds most of the relevant documents. Claimant teams must extract the case from a record the other side designed.
Certification and case management
CAT certification, GLO applications, and US class certification each require detailed factual submissions on commonality and suitability early in the case.
Long timelines, changing teams
Group actions run for years. Institutional knowledge must survive changes in personnel on both sides.
A Case Model built for
class actions and group litigation.
At upload, Crimson maps the parties, events, disputed facts, claims, defenses and evidence in your matter into a structured Case Model with full provenance. Every workflow below runs on that model.
Map common issues to the evidence
The Case Model links each common issue to the defendant documents, expert evidence, and claimant testimony that bears on it.
Extract the case from the defendant's record
Interrogate the defendant's key documents by issue, product, period, and decision-maker rather than by keyword alone.
Organize cohort and lead claimant evidence
Keep the evidence of representative claimants structured by cohort, and test it for consistency with the class-wide case.
Preserve institutional knowledge
The Case Model persists for the life of the matter with full provenance, so new team members inherit the established understanding rather than rebuilding it.
Draft certification and trial submissions
Produce first drafts of factual submissions with each assertion referenced to the underlying document.
Questions Crimson answers,
cited to the page.
Illustrative questions from class actions and group litigation matters. Crimson traces each answer to the supporting document, page, and passage.
- Which internal documents show the defendant was aware of the defect before the product was recalled?
- Compare the lead claimants' evidence on reliance with the defendant's marketing materials.
- Build a chronology of internal risk assessments relating to the practice in issue.
- Identify every decision-maker involved in approving the terms applied to the class.
- Summarize the parties' positions on commonality with the evidence each relies on.
Common questions from class actions & group litigation teams.
We designed Crimson around the merits record: the common issues, the defendant's document production, and the representative claimant evidence. Teams typically pair it with their claims management or book-building systems and bring the cohort evidence into the Case Model where it bears on the common issues.
