Filing of a Consolidated Complaint: Approximately Six Months After Initial Filing of the Avantor Class Action Lawsuit
- Lead Plaintiff Appointment: After the appointment of lead plaintiff, the court will enter a scheduling order which will include a time, usually about 60 days, for the lead plaintiff to file a consolidated complaint consolidating the allegations all complaints along with any new additional allegations.
The Defendants Motion to Dismiss: Decided Nearly a Year After the Avantor Class Action Lawsuit
- Motion to Dismiss Briefing Schedule: In the same scheduling order, the court will also set a time for the defendants to file a motion to dismiss and schedule a briefing and possibly a hearing on the motion once the briefing is completed. The defendants may have 45 to 60 days to file the motion to dismiss and then the briefing schedule is typically around 60 days, and the court will then enter an order either granting or denying the motion to dismiss.
- One Year Has Passed: Thus, by the time defendants’ motion to dismiss is decided nearly a year has passed since the filing of the original complaint and could be possibly longer given the court’s schedule.
Completion Of Discovery: Two-and-a-Half-Years After Initial Filing of the Avantor Class Action Lawsuit
- Discovery Phase: If the defendant’s motion to dismiss is denied, the parties will move into the discovery phase including the exchange of documents, request for admissions, interrogatories, depositions, and third-party subpoenas, among others.
- Uncovering Facts: It allows both parties to obtain relevant information that may not be readily available, helping to clarify the issues at hand.
Settlement Negotiation and Mediation
- Settlement Negotiations Heat Up: By now two-and-a-half to three years have passed since the initial filing of the Avantor class action lawsuit. However, it is at this point that nearly all securities class actions result in a settlement, but that process takes time also. Once the parties have reached an agreement, it will have to be preliminarily approved by the court with notice to shareholders with the right to object, obtain final approval of the settlement, and then the claims process begins.
- Third Party Administrator: Usually, a third-party administrator is hired to administer the common fund. If the parties have complied with all the steps for approval, the judge will approve the distribution of the settlement fund by the claim’s administrator. You will receive a court-appointed notice and have to send in a claim form confirming your purchases and sales. This process alone can take up to a year and therefore it may be four years until the case is finally resolved.
