Real Estate Litigation

In 2019, Kirby's clients prevailed on all claims against them following a two-week jury trial.  The dispute arose out of the sale of a home in Rancho Santa Fe.  The buyers alleged that Kirby's clients failed to disclose plumbing leaks and mold conditions in the real estate disclosure forms.  The buyers alleged fraud, active concealment, negligence, and breach of contract.  The jury rejected all theories of liability against Kirby's clients.  In post-trial motions, Kirby's clients were awarded more than $400,000 in attorneys' fees and costs as the prevailing parties.

Kirby's client prevailed on all claims against it in a two-week arbitration.  The dispute arose out a build-to-suit development project for a commercial tenant.  Kirby represented the developer and the issue was whether the operative development contracts required the developer or the tenant to pay more than $500,000 in impact fees due to the City of Carlsbad.  Both sides were convinced that the contract shifted impact fees to the other.  Kirby's client prevailed in convincing the arbitrator that his client's interpretation of the contract was correct.  The arbitrator awarded more than $500,000 to Kirby's client.

Kirby represented an out-of-state real estate developer that had contracted with the Federal Government to construct the FBI's new office complex in Sorrento Valley.  The dispute arose out of the neighbor's easement over the FBI's intended parcel.  The case was successfully resolved through a confidential settlement that cleared the way for construction to proceed.  Kirby was a guest of honor at the grand opening of the new FBI complex and the firm was publicly recognized for helping save the project.

Kirby represented the general partner in a limited partnership dispute over the acquisition and development of three unrelated parcels in Arizona.  The case was resolved through a confidential settlement.  

Kirby represented a land developer that had to initiate litigation to enforce his option contracts to purchase a series of residential parcels.  The case was resolved by settlement and cleared the way for the new housing development.

Business Litigation

In 2018, Kirby's clients prevailed in a multi-week arbitration that extended over three months.  The dispute arose out of a written contract that Kirby's clients signed whereby they agreed to pay an unlicensed mergers and acquisition (M&A) company a multi-million "deal fee" on the sale of their pet food company.  The M&A company was seeking more than $4 million as a deal fee and prejudgment interest of more than $2 million.  The M&A company lost on all claims against Kirby's clients.  While no case would have ever been brought against the M&A company absent Kirby's clients being sued, Kirby's clients also prevailed on their cross-claims in the arbitration which resulted in a six-figure damage award as well.  In post-arbitration proceedings, the arbitrator awarded Kirby's clients more than $1 million comprised of damages, prejudgment interest, attorneys' fees, and costs.

Kirby's client prevailed in an arbitration brought against her after she refused to pay the amount due under a written contract and a promissory note to purchase a dental practice in La Jolla.  Kirby's client alleged that her signature on the written contract and promissory note had been procured by fraud after it was discovered that the seller had misrepresented the financial condition of the dental practice.  The arbitrator agreed that Kirby's client had been defrauded.  As such, the sale transaction was set aside and the seller received none of the money she was claiming.    

Kirby's client prevailed in an employment arbitration.  Kirby represented the former Chief Executive Officer (CEO) of a medical device company who had been wrongfully terminated.  More than $500,000 was awarded to the former CEO for damages and attorneys' fees.

Kirby's clients prevailed in defending against the allegations of the former Chief Executive Officer (CEO) of a bank seeking close to $20 million as a golden parachute payment due under his employment contract.  After a series of procedural mistakes and the CEO's refusal to abide by the trial court's orders, the case was dismissed with prejudice without ever making it past the demur stage. See, Hall v. Warren Properties, Inc., 2015 WL 865350 (2015).  

Sexual Abuse Litigation

In 2018, Kirby's client was awarded $2.1 million by a jury against the San Diego Unified School District and its former teacher and volleyball coach, Toni Sutton.  The female teacher had sexual relations with a male student in her classroom.  Kirby's client alleged that the school district negligently supervised the teacher and the minor student.  The jury's verdict was the second largest sexual abuse jury verdict in California in 2018.

Kirby began a trial against a school district where a minor child had been sexually abused by other minor students in a school bathroom.  The mother of the child, acting has her guardian ad litem, alleged that the school was responsible for the negligent supervision of her children in between classes.  The case settled on the first day of trial for a confidential amount.

Personal Injury Litigation

Kirby recovered more than $1 million in a settlement for a construction worker that was hired directly by a homeowner in Rancho Santa Fe without securing worker's compensation insurance for the worker.  The worker had fallen off the second story of the home while working and there were not adequate safety precautions taken to protect the worker.  

Kirby won a defense jury verdict defending San Diego Gas & Electric against multi-million damage claims in a wrongful death and personal injury action involving one of its utility poles.  

Kirby has filed and successfully settled numerous personal injury settlements for injured drivers, pedestrians, and bikers in automobile injury cases.  

Investment Fraud Litigation

Kirby's clients were awarded more than $2.3 million by a San Diego jury after Kirby proved that they had been defrauded in a ponzi scheme.  The defendants had defrauded a number of elderly investors, including Kirby's clients, of their retirement savings.  The verdict included an award of punitive damages against the defendants.  Following Kirby's jury verdict, Kirby assisted with providing relevant information to federal authorities investigating similar claims.  A number of the defendants involved in the case were then prosecuted by federal authorities and some remain in prison to this day.   

Probate Litigation

Kirby was lead counsel in a highly contentious family dispute over the control and management of a privately-held corporation holding more than $40 million in family investments.  The case was resolved pursuant to a confidential settlement agreement.  Kirby's ethical conduct was the subject of both the majority and dissenting opinions in the seminal case, McDermott Will & Emery LLP v. Superior Court , 10 Cal.App.5th 1083, 217 Cal.Rptr.3d 47 (2017). 

Banking Litigation

Kirby was heavily involved in the defense of numerous bank officers and directors against the allegations made by the Federal Deposit Insurance Corporation (FDIC) after a local bank was closed by it the Office of Thrift Supervision (OTS).  The alleged losses were more than $1 billion.  After numerous depositions were taken of the escrow officers involved, the FDIC realized that the bad-actors were other persons within the bank and not Kirby's clients.  Most of Kirby's clients were dismissed and others resolved the litigation for nominal amounts.   

After a bank entered into a stipulated judgment for more than $500,000, the judgment was later acquired by a third-party.  The third-party that acquired the judgment sought to collect upon it against Kirby's client.  The case was dismissed without leave to amend after a demurrer was sustained.  The published case is Cadle Co. II, Inc. v. Sundance Financial, Inc., 154 Cal.App.4th 622, 64 Cal.Rptr.3d 824 (2007).
