  • Biography

    Leon Silver is managing partner of Gordon & Rees' Phoenix office. He is the firm’s National Practice Group leader for the Retail & Hospitality and Government Regulatory & Administrative Law practice groups.  A trial lawyer with more than 30 years’ experience handling complicated business and real estate related disputes, he is also a member of the firm's Commercial Litigation, Trial Practice, Class Action, Securities Litigation, Employment, and Privacy, Data & Cybersecurity practice groups. Mr. Silver has a proven record of success in the most difficult, high dollar disputes the firm's clients have faced.

    An accomplished trial lawyer, Mr. Silver is member of the American Board of Trial Advocates, one of the premier legal associations of trial lawyers in America, membership in which is extended by invitation only to experienced trial lawyers who have mastered the art of advocacy and whose professional careers have been marked by the highest standards of ethical conduct, professionalism, civility and collegiality.

    Mr. Silver represents national and multi-national retailers, restaurants, hotels and management companies, government regulated entities, utilities, sophisticated real estate investors and developers, small businesses and business people. As leader of the firm’s Retail & Hospitality and Government Regulatory & Administrative Law practice groups, he provides counsel to his clients on all aspects of their business operations, with a special expertise in the protection of proprietary information, privacy and data security, preventing or protecting clients from government over-reach or over-regulation, employment issues  and in the prosecution or defense of "high stakes", “bet the company” and other high-dollar business tort litigation.

    Examples of his successes on behalf of clients include:

    • Obtained a defense jury verdict on an $11 million claim by a vendor for alleged wrongful returns, unearned discounts, and breach of the duty of good faith and fair dealing regarding the sale of vendor’s power products (scooters, generators, lights) in client's stores. Jury agreed with our view that balance of the account was only $10,733. The decision was over-turned by a split panel of the Arizona Court of Appeals, which subsequently rejected his client's attorneys' fee claim. Mr. Silver successfully petitioned for review by the Arizona Supreme Court twice, and in each instance obtained a reversal of the Court of Appeals ruling and, ultimately, a victory for his client.

    • Successfully prevented an attempt to place his client's recycling plant into Receivership and fended off claims for damages in the tens of millions of dollars arising from alleged fraudulent activity associated with the solicitation of investment capital in the company. The dispute involved litigation in both Arizona and Florida, investors from several different Central and South American countries, and allegations of money laundering, embezzlement, fraud and racketeering activity.

    • Reversed a $400,000 Department of Homeland Security Administrative Law Judge ruling against his client on appeal to the Ninth Circuit arising from an illegal Immigration and Customs Enforcement raid on the client’s restaurants.   The client walked away with a $100,000 attorney fee payment to the client by the government in full resolution of the case. 

    • Successfully prevented a government agency from obtaining disgorgement of tens of millions of dollars of revenue from the firm's client based on a alleged violations of government regulations regarding how public works companies may be operated.

    In addition to his practice, Mr. Silver is a frequent public speaker and author. An accomplished artist, Mr. Silver's paintings have been featured in magazines and can be found in offices, homes and public spaces across the country.

    • Led a multi-office team that successfully prevented the implementation of a receiver and attempted foreclosure of a client's newly developed recycling plant.  His team identified a number of suspicious financial transactions, involving parties in several countries, and being funneled through Miami entities. This led to the filing of a counterclaim alleging fraud, Civil RICO claims, and various business torts, in the existing Arizona action and a threatened Federal Lawsuit to be brought in Miami against several related parties who resided both within the United States, and in Colombia, Venezuela, and the Dominican Republic. The aggressive pursuit of the counterclaim and threatened Miami lawsuit led quickly to a favorable settlement for the client.
    • Successfully negotiated a nominal settlement payment in response to a $3+ Billion claim brought by the Michigan Attorney General against a textile recycling client accused of falsely soliciting clothing donations on behalf of a local charity. Under the pressure of a Gubernatorial Campaign focused on shutting down fraudulent charitable solicitors, Mr. Silver was able to convince the Attorney General that his client was a legitimate recycling organization, committed to its mission of eliminating waste and improving the environment while supporting deserving charitable organizations.
    • Obtained summary judgment against consumer plaintiff in no-injury/no-accident class action alleging consumer fraud because seat belts allegedly false latched.
    • Developed an international, multi-jurisdiction litigation strategy that led to the successful settlement of several complex lawsuits on behalf of our client. Mr. Silver conceived of and directed the filing of claims against a number of affiliated entities in five separate lawsuits in U.S. and European courts. After vigorously litigating this matter for more than two years, successfully overcoming jurisdictional and other Rule 12 challenges, and defeating a preliminary injunction counterclaim in one of the cases, Mr. Silver's team negotiated a favorable settlement of all claims and counterclaims.
    • Immediately after opening statements in a federal jury trial, the vendor – despite claiming more than $30 million in damages – agreed to client's pre-trial settlement offer for amounts due on an alleged requirements contract for rebuilt alternators and related products.
    • Client retained ownership in a dispute between founders of two yoga studios as to who had the rights to continue operations in facilities and to the customer lists.
    • Obtained a $1.5 million award in client’s favor on a counterclaim against a vendor plaintiff that was seeking $2.5 million on its account.
    • Obtained a significant attorney fee award in favor of medical practice client in a business divorce case, despite the arbitration panel finding that money was owed to the departing doctor. The result was a net payment in client’s favor.
    • Successfully prosecuted a breach of contract claim against retail client’s pay phone vendor for repudiating exclusive pay phone installation and service contract for phones at all 1,100 of client's stores.
    • Successfully prosecuted a lost profits claims against general contractor, and coverage claim against insurer through trial where contractor’s sub caused client's national specialty parts call center to be shut down for a day by allowing lacquer fumes to circulate through the building’s air conditioning system.
    • Successfully challenged several years of CAM allocations charged to restaurant client and obtained attorneys' fees awards through all levels of trial and appeals.
