How do you start a class action lawsuit?

There are a few things consumers should know about how to file a class action lawsuit. In order to start a class action of any kind, a person must have a cause of action that is shared by a significant number of others. The class action lawsuit is based on the old principle of strength in numbers and allows a large number of plaintiffs to bring legal action against a powerful defendant when individual lawsuits are not practical.

That said, the entire process begins with a single plaintiff or a small group (two to three) individuals who have suffered the same harm by the defendant.

Who Is Eligible to File a Class Action Lawsuit?

Virtually anyone with a valid cause of action can start a class action lawsuit, provided they meet certain qualifications. Primarily, this means the one who files must demonstrate a number of things, which are defined under Federal Rule of Civil Procedure Number 23:

  • Adequacy — Is/are the lead plaintiff(s) able to represent the class in a fair and adequate manner?
  • Ascertainability — In other words, can all potential plaintiffs be identified?
  • Numerosity — Are there enough plaintiffs to justify granting class status?
  • Commonality — Do all plaintiffs have the same cause of action?
  • Typicality — Is/are the class representative(s) typical of the other class members?

In addition to the above, the lead plaintiff(s) must prove the cause of action is serious enough to warrant the court’s involvement. Furthermore, the class representative(s) must be able to answer affirmatively to at least one of three questions raised under Rule Number 23(b):

  • would filing separate, individual lawsuits create a risk of inconsistent verdicts?
  • would a court order (injunctive or declarative relief without the involvement of a jury) be appropriate in light of the cause of action as it relates to all class members?
  • are there common questions of law that would make a class action preferable to individual lawsuits?

Any injured party who can meet the above requirements is eligible to start a class action lawsuit.

How Many Plaintiffs Are Required to File a Class Action Lawsuit?

How to start a class action lawsuitThere is no hard and fast number. A class action may be started by one individual, or a dozen. All that is necessary is that all potential plaintiffs have the same cause of action, i.e., the same specific complaint against the defendant. The one who initially files the class action typically becomes what is known as the “lead plaintiff,” and will have many additional responsibilities — but that person also gets an extra share of any settlement, provided the class action is successful.

 What Happens After a Class Action Has Been Filed?

Once the papers have been filed, the case goes before a judge, who will review the complaint and determine whether there is a sufficient number of plaintiffs with the same cause of action as well as other factors. If the judge determines that the case has merit and there are enough qualified petitioners, s/he will allow the case to move forward.

Are There Financial Incentives for a Lead Plaintiff?

As noted earlier, the lead plaintiff is entitled to extra compensation for working closely with the attorney(s), attending all court proceedings and generally representing the other class members before the judge and jury.

How Much Does It Cost to File a Class Action Lawsuit?

Typically, there are no up-front costs to start a class action lawsuit. Once they have determined that the case is strong enough, lawyers who specialize in this type of litigation represent the class on a contingency bases, meaning they front all initial costs of filing and moving the case forward.

If the case ends in a settlement or a verdict in favor of the plaintiffs, the lawyer(s) take a percentage of the judgment (generally one-third). It is a risk for them as well as the lead plaintiff(s), because if the defense prevails, they receive nothing.

What If Some Class Members’ Complaints are Different?

If all plaintiffs’ cases are not identical, this is not necessarily a deal breaker. Such a situation is covered under Federal Rule of Civil Procedure Number 23(c)(4), which allows for the establishment of “subclasses.” Forming subclasses is appropriate under the following circumstances:

  • Some class members are seeking different relief than others — for example, some plaintiffs want the defendant to pay for health monitoring, while others are seeking monetary compensation
  • Some groups among the class members have slightly different, but related facts
  • There are groups from different jurisdictions with varying rules of evidence

While a class action can be sustained with a few subclasses, too many may result in a decision by the court to deny class certification  on grounds that “common questions [of law] do not predominate.”

How Long Does It Take to Resolve a Class Action?

There is no good answer to this question. While some class action lawsuits can be resolved in a few months, many of them go on for two years or more. It all depends on the strength of the claim, preponderance of evidence and the complexity of the case.

Ideally, lawyers on both sides will be able to negotiate a satisfactory settlement before the case goes to trial; this is considered the best outcome in most cases. The only drawback is that typically, when a defendant agrees to a settlement, they are not required to admit any liability or wrongdoing.

What Is the Difference Between a Class Action and Multidistrict Litigation?

While both involve multiple plaintiffs, the parties in a class action are legally considered to be a single plaintiff.  In multidistrict litigation (MDL),  plaintiffs share judicial resources and pre-trial procedures (such as discovery, expert testimony, etc.), but retain their individual lawsuits.

What Does a Person Need Before Approaching an Attorney?

Most lawyers and firms specializing in class action litigation offer free initial consultations, either in person, online or over the telephone. During this session, the lawyer will want to make certain that the claim is a valid  one, as cases deemed to be frivolous tend to be dismissed quickly.

One  should be prepared to provide documentation of the complaint (such as photos, receipts, etc.) before they start a class action lawsuit. The lawyer will then research similar past cases and attempt to learn whether or not any laws have been broken, and how many other people have been affected by the same kinds of issues.

Class action lawsuits can be filed in myriad areas, including civil rights, defective products, medical problems, false claims and more.

    Hello, i recently had my car impounded by Wilsons towing in San Bernardino Ca. They said it was initiated by the SBPD and it was next to impossible to retrieve not just financially. I had the car parked for a number of reasons and it should have never disappeared from the front of my house. I read somewhere i was supposed to be warned 72 hrs in advance for vehicle violations and if i didnt move the vehicle it would be towed. I nvr received that warning nor was i informed after it was towed. Wilsons makes it so hard to retrieve a vehicle, they are shady and ruthless money wanting monsters of the community that prey on our cars everyday. I know many people have been wrongfully towed and lost money or cars to them. We need to bring them to justice. Lets shut their illegal practices down! Join me if you have been wronged by them and if any attorneys can help, id greatly appreciate speaking to you. TGIF

    Our group is seeking an attorney for a consultation regarding claims against Honda for paint issues. There have been recalls in the past regarding these issues but they are spotty and do not cover all vehicles that are having the issues. We have a Facebook group with a LOT of angry Honda owners. If there is an attorney or a firm that can give us a consultation, please contact me. Thank you.

    I made a purchase from spoiledChild for a bottle of liquid collagen, it showed that the next refill date as 8/23 but I wanted the item shipped out now. When I tried to make the correction I was charged again. I contacted their customer service and was told that I should not have selected auto-refill and they kept my money. This was the second time that this has occurred.

    I would like to file a class action lawsuit against the company that I previously worked for. The company worked us many hours of overtime but only paid us straight time for this. In the rule book it states that any hour over 40 or over 80 would be paid at time and a half I made a copy of the rule book paper that it is written on. Also while I was employed after my 90-day probation period was up I put in for 3 Days of sick pay and did not receive it because I quit after the put the three days of sick time in it was clearly after my 90 day probation. Was over. In the states in the handbook once again that after 90 days on the 90th day you would be entitled to your sick days your vacation time and your personal days but I was not paid for that I realized that I would not be paid for my vacation upon leaving that would be up to the company and of course they did not pay me. But my problem is the overtime I work then that was not paid for it. I am not the only one at the company that just happened to I know of three other people one other person was promised a certain pay for a certain position and was not given that pay they are willing to be in on the class action suit I don’t know about other employees I have not approached them.

    I would like to start a class action against Ibotta. They consistently short you in the rebates either due to faulty systems and/or other reasons. They then force you to follow up and prove it for very small amounts. Reading the reviews leads me to believe that others have experienced this as well.

    I am accusing iRobot of knowingly selling products that fail. I purchased a $900 Roomba i7+ in January of 2021. (Luckily, I paid extra for a 2 year warranty through SquareTrade. The mfg warranty is only a year.) My Roobma has been in the shop 3 times and replaced once. Now my extended coverage has expired. I contacted iRobot and they will not help, except to promote their new every two rental program for Roomba products. Even with all the failures I’ve experienced with my personal Roomba, what convinced me that iRobot puts out garbage machines is when, after testing a new Roomba for iRobot with similar failures, I saw that an identical/similar model was available to consumers to purchase. I tested their new iRobot for 6+ months and it also had chronic trouble, had to be replaced, needed parts sent to me, and they finally had me turn it in because it suffered from the same trouble that I had with my own personal bot. iRobot sells garbage, knowing that it is going to fail.
