Representative Matters

Representation of Public School Districts

Hall is experienced in the challenging environment of public school districts facing charges of negligence arising from alleged abuse of minor students. He has supported multiple trial teams in briefing issues before trial and appellate courts, drafting jury instructions and providing counsel on trial tactics, with a particular view toward preservation of error for appellate review. In two cases, Hall’s client received a defense verdict after multi-week trials. Hall’s roles in these matters included preparation of pre-trial briefing, drafting of jury instructions and special verdicts, arguing proposed jury instructions and post-trial motions, and providing strategic counsel to trial teams during the preparation phase, trial phase and post-trial phase.

Product Liability

From the outset of his practice to the present, Hall has had the privilege of participating in some of the major episodes of mass tort litigation regarding pharmaceuticals and medical devices. He has represented defendants in diethylstilbestrol (DES), Dalkon Shield, DPT and polio vaccine, TMJ Teflon implant, Bendectin, Vioxx, breast implant litigation and major medical device litigation (including prosthetic hip systems and anesthetic delivery systems). In this field, Hall has had perhaps the most impact in developing the law before the nation’s appellate courts in this challenging environment for manufacturers and distributors:

  • Daubert v. Merrell Dow: Hall represented the manufacturer of Bendectin, the only FDA-approved therapy for morning sickness, in the landmark U.S. Supreme Court case that established the trial court’s obligation to act as a “gatekeeper” to exclude unreliable expert testimony. 
  • Sindell v. Abbott Laboratories: The DES litigation posed an intriguing challenge to the California Supreme Court concerning under what circumstances would the children of women who could not identify the manufacturer of an anti-miscarriage therapy be allowed to proceed in the pursuit of a product liability claim. Hall represented the manufacturer who took the lead in advocating the industry’s position regarding “market-share liability,” and this opinion is the landmark on the subject.
  • Merrell Dow v. Havner: While Daubert spoke to the admissibility of expert testimony under the Federal Rules of Evidence, many state courts of last resort focused on fashioning like rules, following the lead of the U.S. Supreme Court. In this case, Hall, again representing the manufacturer of Bendectin, urged that the Texas Supreme Court adopt the rationale of Daubert and overturn a $33 million dollar verdict which was based on unreliable “meta-analysis” of epidemiological data on congenital birth defects and in vitro animal studies. The Texas high court agreed, reversed the judgment and ordered that judgment be entered in favor of the manufacturer.
  • Toole v. McClintock: At the beginning of the nationwide breast implant litigation, the manufacturers were reeling from a wave of bad publicity and adverse verdicts. In this case, where Hall represented appellant Baxter Healthcare Corporation, the 11th Circuit reversed a multimillion dollar judgment, which helped turn the tide against a swell of judgments in the plaintiffs favor.
  • Mack v. Stryker Corp: This is one of three significant appellate victories for a major medical device maker, securing affirmance of the grant of summary judgment in our client’s favor on the issue of the presence of a product warning defect given the state of scientific learning at the time the device was prescribed. Sedgwick’s client, alone among major manufacturers in the market, has not suffered an adverse outcome before reviewing courts in cases involving this product. 
  • One of the first appeals in California of a breast implant case was handled by Hall, resulting in the affirmance of a judgment in favor of his client. 
  • Successfully represented the manufacturer of the leading anti-anxiety therapy when the California Court of Appeal affirmed a judgment following a jury trial for the defendant.
  • Represented the parent corporation of a major breast implant manufacturer in proceedings around the country, including the multi-district litigation proceeding, concerning whether the parent was a proper party-defendant in those cases.
  • Represented the defense in mass tort litigation involving tobacco (including a published California appellate opinion on the controversial limitations/revival statute), asbestos and benzene exposure litigation.
  • Represented the defense in mass tort litigation involving heavy machinery, handheld small tools and environmental contamination. 
  • After preparing a summary judgment motion for a manufacturer of a wood-working table router on the grounds of post-sale modifications, the plaintiff accepted a settlement from Hall’s client of less than one tenth of further costs of defense.
  • As an element of his practice in mass tort defense, Hall has represented his clients in connection with many of the administrative challenges of multi-district litigation on the federal level, and coordinated litigation at the California state level. He recently represented a drug manufacturer in a landmark 9th Circuit opinion curbing the abusive practice of joining hundreds of plaintiffs in state court class actions to avoid removal under the Class Action Fairness Act.

Professional Liability Experience

Another area of emphasis in Hall’s practice has been professional liability, particularly in the representation of attorneys. A disturbing trend in legal malpractice litigation has been the willingness of clients to sue counsel as “safety nets” for the clients’ endeavors, to insulate them from the risk of transacting business. 

  • Berg & Berg Enterprises, LLC v. Sherwood Partners Inc.: Hall successfully represented counsel in a lawsuit brought by an adversary who claimed a conspiracy between counsel and its client harmed the adversary. In the definitive published opinion on the California statute that requires judicial prescreening of such claims, the Court of Appeal adopted Hall’s construction of the statute, and reversed the trial court’s determination to permit the lawsuit to proceed against Hall’s client. 
  • In both trial and appellate forums, Hall has represented lawyers in such varied matters as negligence, malpractice, malicious prosecution and fraud claims, as well as litigation concerning the California “anti-SLAPP” statute, which requires an early merits evaluation of lawsuits based on activity that petitions governmental entities, and attorney disqualification motions. 
  • Tried professional liability actions for lawyers involving alleged securities wrongdoing, and malpractice in corporate formation. 
  • Retained to counsel and represent attorneys even before a professional liability lawsuit has commenced, to assist in the management of risk and exposure in cases where malpractice allegations may ultimately ensue.  

Hall has represented other professionals, such as physicians, dentists, accountants, engineers and appraisers: 

  • While representing a dentist on appeal from an adverse judgment following a jury verdict, Hall successfully urged not only that the verdict should be reversed, but that judgment actually be entered in his client’s favor, based on the wrongful denial of a motion for judgment notwithstanding the verdict, because of the expiration of the limitations period. 
  • Hall is a member of the firm’s healthcare practice group, and has represented its clients on appeal (preserving the rights of a healthcare management group to assert privacy rights on behalf of its members), and in trial courts (concerning the ability of a hospital group to unilaterally cancel a contract to provide services to healthcare plan enrollees).

Employment Experience

As a member of the firm’s employment and labor practice group, Hall has represented employers in a variety of lawsuits, ranging from racial, gender and age discrimination, sexual harassment, and other types of wrongful termination. 

  • Represented on appeal a major Los Angeles law firm in defending a wrongful termination suit arising from an alleged affair between the daughter of the firm’s managing partner and the dismissed employee; summary judgment for the firm and the partner was affirmed on review. 
  • Represented the District Attorney of Los Angeles, and several subordinates, in a suit brought by a deputy who alleged sexual harassment and gender discrimination resulting in a failure to promote. The Court of Appeal affirmed summary judgment in favor of Hall’s clients. 
  • Represents a major hair care, hair color and cosmetics manufacturer in employment matters.

Commercial Litigation

Over his career, Hall has handled several different types of commercial disputes:

  • Represented the general partner of a substantial Beverly Hills residential real estate development in a dispute with limited partners, and helped secure a multimillion dollar settlement for his client. 
  • Secured a temporary restraining order in district court on behalf of a national managed care provider preventing the termination of a county-wide contract with hospitals, which threatened interruption of service for hundreds of Medicare Advantage insureds.
  • Represented a Southern California automobile dealer in federal court litigation over the wrongful deprivation of sales territory by a “big three” car manufacturer, also resulting in a multimillion dollar settlement for the dealer. 
  • Advocated on behalf of a major European pharmaceutical manufacturer in a joint venture dispute with a start-up company concerning a diagnostic technique for cervical cancer, yielding a favorable settlement for his defendant client. 
  • Handled a patent infringement suit concerning intra-ocular lens implants on behalf of a major European pharmaceutical manufacturer.
  • On behalf of his hair care client, Hall has handled a range of commercial disputes with vendors, suppliers and distributors, including a dispute arising out of the acquisition of major domestic hair care manufacturer. 
  • On behalf of another hair care manufacturer, Hall provided both representation and counsel in a dispute between the principals of a joint venture, leading to a buyout of one of the principals by Hall’s client on favorable terms. 
  • Hall has handled a number of breach of warranty claims for clients such as automobile manufacturers, paint suppliers and bulk plastic suppliers. 
  • He has handled several licensing suits, including claims against his clients for misappropriation of likeness, and distributorship disputes. 
  • Represented clients in a number of controversies concerning real property. 
  • Hall has experience in anticompetitive tort litigation. He represents the largest publisher of Chinese ethnic phone directories in Southern California in a high stakes suit brought by a competitor, whose intention, as found by a bankruptcy court, is no less than to put Hall’s client out of business. He recently secured an order that the client’s adversary pay over $1.5 million in attorney’s fees to his client. Hall’s client continues to prosper in the marketplace.
  • Tried a federal court jury trial where his client was accused of fraud in connection with the purchase and sale of utility-grade power transformers. Where the client admitted liability to the plaintiff, Hall successfully argued to the jury that the award should be less than one tenth of the amount sought by the plaintiff.
  • Hall has handled a number of commercial disputes concerning intellectual property. For example, on appeal he represented two former employees, and an investor, who were sued by the former employer for misappropriation of trade secrets, primarily customer lists. Summary judgment was granted in favor of Hall’s clients, and affirmed on review.
Surety, Fidelity and Insurance Litigation
While surety and fidelity practice is a specialized area, Hall’s background as a generalist has contributed to the representation of this firm’s clients in this group in a number of cases on appeal:
  • A surety for a contractor on Los Angeles’ subway project was found jointly and severally liable on a multimillion dollar judgment based on an evidentiary sanction against the contractor. On appeal, Hall successfully argued that the judgment had to be reversed on due process grounds. 
  • Hall secured the affirmance of a summary judgment in favor of the issuer of financial institution bonds. 
  • In another appeal, Hall secured the reversal of summary judgment against the issuer of a public works payment bond. 
  • In a series of published opinions, Hall represented the issuers of construction payment bonds and stop-notice release bonds. 
  • Hall has also represented many insurers in coverage and extra-contractual liability litigation. He represented an insurer on appeal concerning whether a comprehensive general liability insurance policy, with advertising injury coverage, required a defense for an insured sued for trademark infringement.

Appellate Practice

Hall has handled well over 150 appellate matters before both federal and state courts of review. He has secured reversals of multimillion dollar judgments against his clients, and has successfully defended scores of defense judgments on review. He has also represented clients in original proceedings before appellate courts. He has participated in more than 45 matters which resulted in published opinions by the U.S. Supreme Court, the 1st, 6th, 8th, 9th, 10th and 11th Circuit Courts of Appeals, as well as the California Supreme Court and California District Courts of Appeal, among others. He is certified as an appellate specialist by the California State Bar Board of Legal Specialization.
