Continental Connection (Colgan) Flight 3407
John was a key member and leader of e-discovery issues arising from the February 12, 2009 crash of Continental Connection Flight 3407 in Clarence Center, New York.

Data Breach Response
John was contacted following a data breach involving 158,000 potentially affected persons resident in all 50 states and Puerto Rico. John took over coordination of the response from another law firm. John was able to reduce the client’s breach response costs by $150,000 over initial notice and reporting estimates through coaching of public relations and customer messaging; focusing the computer forensics team on evidence of access and acquisition; and analysis of nuances in all applicable data breach notification laws.

Information Governance Project
John led a full day workshop to explore the strategic data security vision of a multi-billion-dollar web based services company, and providing legal support for a multi-year project to develop an IT security and governance maturity model, which involved participation by the CEO, CIO, CISO, data security team members and an internal audit team.

Information Governance Project
A U.S. based Fortune 500 manufacturer with worldwide facilities and strategic partners came to John for advice on moving to the cloud to share information with its employees and strategic partners, worldwide. John worked with the project team to develop legal safeguards, processes for managing access to the environment, preservation for litigation business processes and governance of documents stored in the environment.

Information Governance Project
A U.S. based company with over 10,000 employees wanted to implement Microsoft’s Yammer™ for its employees. John developed an information governance strategy for the environment, including providing a legal opinion in support of information management and preservation processes for implementing legal holds on relevant information within the environment.

Information Governance Project
A nationwide owner of nearly 100 long term care facilities came to John to develop and implement a comprehensive information governance strategy, including development of information management policies and procedures, a records retention schedule, legal hold business process, roll-out and implementation plan. John also conducted an initial round of training that was recorded and is now shown to all new employees.

Kniery v. Cottrell, 59 AD3d 1060, leave denied 61 A.D.3d 1439
John obtained a unanimous reversal and dismissal of this wrongful death action based on products liability. By persuading the appellate court to apply the correct (yet complex) choice of law analysis, the court dismissed the lawsuit due expiration of a ten-year statute of repose of an adjoining state, even though decedent was a New York resident.

Frame v. CSX Transportation, Supreme Court, New York
John won summary judgment and dismissal of the claim of a dirt bike rider that struck a wire strung between two poles, arguing application of New York’s Recreational Use Statute (General Obligations Law § 9-103) (landowner is immune from liability for third-party’s use of land for recreation) and overcoming a known exception to the rule that permits a suit to proceed if a landowner knew or should have known that injury could result by stringing a wire or chain across a pathway.

Humphrey v. Riley, US District Court Northern District of New York
Humphrey’s complaint alleged several causes of action against John’s client stemming from his deceased wife’s use of the Mirena intrauterine device (IUD), a contraceptive device designed and sold by Bayer. Specifically, it was alleged that use of the Mirena IUD was “the cause of or conduit for” several medical ailments that she developed, including “a Beta Hemolytic Strep Group A (‘GAS’) infection, pelvic inflammatory disease, pelvic abscess and toxic shock syndrome.” John convinced plaintiff to discontinue the action against the medical device manufacturer prior to dispositive motion practice, including convincing the hospital co-defendants to discontinue all cross claims.

Amherst Station v. General Wireless Operations, Inc., US District Court for the Western District of New York
RadioShack Corporation (“RadioShack”) filed for voluntary debtor relief pursuant to Chapter 11 Bankruptcy of Title 11. General Wireless emerged as the Stalking Horse purchaser of hundreds of RadioShack leased properties nationwide. General Wireless refused to vacate the premises owned by John’s client, Amherst Station (managed by Phillips Edison Co.). Amherst Station commenced a summary eviction proceeding against General Wireless/RadioShack to recover the premises, which was ultimately surrendered during litigation.

Kendall v. Aegis Engineering Services, Inc., US District Court Northern District of New York
Plaintiffs’ claim arose out of an incident when local police dispersed tear gas into their house. Following the incident, plaintiffs filed an insurance claim with their insurer, Amica Mutual Insurance Co., to remediate the building of tear gas remnants. Amica sought out the services of Aegis Engineering Co., an environmental engineering company, to provide Amica with further information on the remediation process. Specifically, Amica asked Aegis to coordinate with the remediation company chosen by plaintiffs to inspect the loss, assess the scope of environmental remediation, determine habitability and report accordingly. John successfully defended the claim against the engineering company for its handling of the matter, including obtaining summary judgment dismissing the claim.

Sero v. CSX Transportation, US District Court for the Western District of New York
Plaintiff was injured while an employee for Davey Tree Expert Company (“Davy Tree”). Davey Tree was under contact with a Class I Railroad to clean up an abandoned railroad yard in Rochester, New York. Plaintiff incurred injuries when he fell into a hole while working in the abandoned railroad yard. The issue before the Court was whether the contract between the railroad and Davey Tree required the contractor to obtain insurance for the railroad, and whether the contract required Davey Tree to indemnify and hold the railroad harmless for the injury to plaintiff. John ensured that liability was passed from the railroad to Davey Tree.

In Re Mirena IUD Products Liability Litigation, US District Court for the Southern District of New York
Hundreds of plaintiffs sued three related companies — Bayer Healthcare Pharmaceuticals, Inc., Bayer Pharma AG and Bayer OY (“Bayer”) — alleging that they were injured when Mirena, an intrauterine contraceptive device manufactured by them, perforated, became embedded in or migrated from their uteruses. These diversity cases were consolidated as part of a multi-district litigation (“MDL”). Plaintiffs brought claims alleging negligence, strict liability, manufacturing defect, design defect, failure to warn, breach of warranty (implied and express), negligent misrepresentation, fraud, and various state-specific statutory violations. John was selected by Bayer to act as state-wide counsel for all matters filed in state and federal court.

Voom HD Holdings LLC v. Echostar Satellite LLC, 93 AD3d 33
John’s experience and national reputation as an expert in e-discovery was called on by Lawyers for Civil Justice to author and file an amicus brief in this multi-billion-dollar battle between two media companies. This case required the appellate court to determine the scope of a party’s preservation duties in the electronic discovery context, and the appropriate sanction for failure to preserve electronically stored information (ESI). This is the first time a New York intermediate appellate court addressed the issue of when the duty to preserve evidence was triggered. The court adopted the standard articulated in the Second Circuit, that once a party reasonably anticipates litigation, it must suspend its routine document retention/destruction policy and put in place a “litigation hold” to ensure the preservation of relevant documents.

Bready and Harris v. CSX Transportation, 19 NY3d 834
Following denial of summary judgment at the trial court level, John obtained reversal from an intermediate appeals court dismissing all claims and validation from New York’s highest court that his client did not breach a duty of care to the plaintiffs even under a higher duty imposed by the Federal Employers’ Liability Act.

McCabe v. CSX Transportation, 27 AD3d 1150
Following the trial court’s erroneous dismissal of all contributory negligence claims against the railroad, John obtained a reversal at the appellate court.

Gehen v. Consolidated Rail Corporation, 289 AD2d 1026
John protected his clients against being forced to pay plaintiff’s costs to attend four out-of- state depositions of corporate witnesses.
