Types of Class Actions

Working for You in Many Areas of Your Life

Our class action lawyers have extensive experience litigating large, complex class actions in a variety of practice areas, including price-fixing, securities, pharmaceuticals or medical devices, consumer protection, product liability, environmental issues, and institutional abuse or humanitarian cases.

Consumer Protection

Misrepresentation of products or services takes advantage of people's trust. We try to reset the field for the consumers who have been misled.

eDiscovery

Siskinds eDiscovery team includes a group of lawyers and project managers with experience collectively providing counsel on the discovery phase of litigation and regul…

Environmental

Careless or illegal actions that damage the environment can impact a large number of people in extensive ways. We can define and seek the compensation required.

Institutional Abuse and Humanitarian

Domestically and abroad, people continue to suffer due to the negligence - deliberate or unintentional - of others. We can apply our legal abilities to their needs.

Pharmaceutical Litigation

When medical devices and medications are not properly tested or risks are not sufficiently communicated, we get the support you unexpectedly need.

Previous Actions

Since 1992, we have been at the forefront of the evolution of class action law.

Price Fixing

Consumers can purchase products that are deliberately over-priced. We aim to correct the deception and recover the overage that consumers paid.

Product Liability

Defective or unsafe products can enter your life through negligent production or misleading claims. Companies are responsible for the integrity of their work.

Securities

Full, fair and timely disclosure of facts is required; if not, we sue companies that violate the Securities Act and seek compensation for investors.
