The lawsuit was filed by The X-Law Group, P.C. and Presidio Law Firm LLP on behalf of residents affected by the chemical tank incident at the GKN Aerospace facility in Garden Grove. The lawsuit was the first filed legal action relating to the GNK incident. It currently includes claims for negligence, private and public nuisance, trespass and ultrahazardous activity. These are allegations only, not findings by a court. The case seeks relief related to evacuations, property impacts, disruption potential impacts on property values; outcomes are uncertain and will depend on the evidence and court rulings.

The primary named defendant is GKN Aerospace Transparency Systems Inc., which operates the facility at 12122 Western Avenue in Garden Grove, along with affiliated companies. Additional entities may be added as defendants as the investigation develops. No determination of responsibility has been made by the court. The facility manufactures aerospace components and stores industrial chemicals, including the tank that holds methyl methacrylate (MMA) at the center of this incident.

MMA is a Class 1B flammable liquid used to make acrylic plastics. It is highly volatile and continuously releases invisible, flammable vapors that can ignite from a small spark, an open flame, or even static electricity. Because MMA vapors are heavier than air, they travel along the ground, which increases the risk of a "flashback" fire reaching the source and causing an explosion. Publicly available information indicates MMA exposure may be associated with respiratory, skin, and eye irritation. This information is provided for general background only and is not medical or legal advice. Individuals should consult medical professionals about symptoms.

Generally, people who lived, worked, owned property, or were present in potentially affected areas and experienced disruption or related costs may wish to submit information for evaluation.

We anticipate offering contingency-fee representation, which means that clients will not pay upfront fees or costs. Other arrangements may be necessary based on the specifics of a given case, but any fee any fee arrangement and payment, if any, would be subject to a signed agreement and, in a class action, court approval. No outcome is guaranteed.

If a class is certified, individuals who meet the court-approved definition would be included in the class and represented for purposes of that case. This description is general information and not a determination that you are included. A named plaintiff, also called a class representative, is an individual who steps forward to formally represent the class in court filings and case decisions. Class representatives have additional responsibilities, but the majority of class members do not.

Class representatives, if approved by the court, often participate in case activities such as reviewing filings or sitting for a deposition. The time commitment varies by case. This is informational only and not a recommendation to serve. If you are interested in serving as a class representative, please let our team know during your intake.

In many class actions, only the names of court-approved class representatives appear in public filings, but practices can vary by court and case. Named plaintiffs (class representatives), however, are identified in the complaint and on the public docket. We take confidentiality seriously and will discuss any privacy concerns with you directly.

Participation may depend on whether you are already represented for this matter and other factors. Prior insurance claims do not necessarily preclude participation. Please share details for a conflicts and eligibility review. This is not legal advice. Filing an insurance claim does not, by itself, prevent you from being part of the class. Please tell our team about any prior legal consultations or insurance claims so we can advise you accordingly.

Participation in a class action and any insurance claims are separate processes, but circumstances vary. Continue to cooperate with your insurer and retain communications. We can review coordination issues, but this is not advice about your policy rights.

The case has been filed and is in early stages. Typical next steps can include service, responsive pleadings, case management, and potential motions related to class certification. The court will determine any next steps. We will provide updates as the case develops.

Class actions can take several years to resolve, and the timeline depends on many factors, including the defendants' response, motion practice, discovery, the class certification process, and any appeals. We cannot predict an exact timeframe, but we will keep class members informed as the case progresses.

Typically, only class representatives and certain witnesses appear in court or sit for depositions, but requirements depend on the case and court orders. Most class members participate without any court involvement at all.

While the class action itself will set formal deadlines as it progresses, deadlines may apply to individual claims. We cannot advise here on specific deadlines. If you wish to be evaluated, consider submitting information promptly so we can review your situation. This is not legal advice about any limitations period. We encourage you to act promptly.

If you submit your information to us, we will keep you informed by email and, where appropriate, by mail or phone. Additionally, if a class is certified, formal notice will be sent to identified class members. Major updates will also be posted on this website.

You can contact us by phone, email, or through the website contact form. We strive to respond promptly, subject to availability. Contacting us does not create an attorney-client relationship.

No. A retainer agreement only covers the individual who signs it. If you are the owner of the property, your signature also covers the property itself for claims tied to the property (such as remediation, loss of use, and diminution in value).

However, every adult household member (anyone aged 18 or over) who wishes to participate must sign their own separate retainer agreement to be represented by the firms. This applies regardless of whether they are listed on the deed or lease — adult occupants, adult children living at home, roommates, and other adult residents each need to sign individually.

While people who lived within the evacuation zone have the easiest way to demonstrate property damages, others nearby may have been harmed. Each situation is fact-specific, and we encourage you to submit your information.

It is normal in a highly publicized event for there to be a “feeding frenzy” response from various attorneys seeking to conduct litigation. Consumers must be wary of inexperienced attorneys filing lawsuits in complicated matters that require experience and resources to deliver the best result possible. Additionally, client care and ethical representation are matters to consider. Here, The X-Law Group, P.C. and Presidio Law Firm LLP have highly relevant knowledge and experience that they bring to bear to the issues that will likely be presented in this litigation, having conducted successful litigation of similar matters such as the Plains Pipeline Oil Spill, the Thomas Fire, and the 2020 Delta Fuel Dump. Their readiness for action is demonstrated in being the first to file, days ahead of most other “copycat” filers.
