CDQ does not believe its clients should have to pay a second set of attorneys who have to learn the case for the purposes of an appeal.  Accordingly, CDQ’s litigation teams are well-prepared to brief and argue any appeal that might be filed against or on behalf of its clients.  CDQ’s team includes multiple attorneys who clerked in federal and state courts, and who ensure that the briefing is accurate and persuasive, both legally and factually, and complies with the ever-evolving technical requirements in the appellate courts both in Arizona and the Ninth Circuit Court of Appeals.  Appellate courts have ruled in favor of CDQ’s clients in multiple recent decisions, including:

Shooter v. Arizona, 4 F.4th 955 (9th Cir. 2021)
State of the Netherlands v. MD Helicopters, Inc., 250 Ariz. 235, 478 P.3d 230 (2020)

Business Litigation, primarily of commercial disputes, is the primary focus of CDQ’s practice. Our lawyers, all of whom are litigators, have vast experience in the resolution of civil disputes. CDQ has represented clients in disputes involving nearly every type of civil dispute, including breach of contract, commercial transactions, securities, construction-related matters, antitrust, insurance (defense, coverage and bad faith), labor and employment issues, products liability, commercial torts (fraud, tortious interference, negligent misrepresentation, aiding and abetting, etc.), defamation and invasion of privacy, racketeering, professional liability, business dissolution, creditors’ rights, principal/agent, fraud, civil rights, constitutional disputes, environmental, special actions (statutory and discretionary), licensing/technology disputes, software design and implementation, copyright and trademark actions, judgment enforcement and nearly every type of real estate matter (including foreclosure, fraudulent conveyance, brokerage disputes, zoning, inverse condemnation/regulatory taking, nuisance, waste, trespass, landlord/tenant, specific performance and rescission/constructive trust). CDQ also handles appeals involving these matters. CDQ is intensely active in counseling its clients on the implementation of internal dispute avoidance procedures and safeguards to reduce the potential for litigation and to minimize any potential exposure. Further, we are firmly committed to the use of early and strategic ADR procedures (e.g. mediation) to resolve disputes efficiently and before they take on a life of their own.

Civil Rights

Legal disputes, especially those involving state actors, often involve an analysis of whether a particular statute, rule or action comports with the requirements of the Arizona Constitution and the United States Constitution and whether the conduct at issue infringes upon a constitutionally protected right. CDQ has frequently represented clients in such disputes. For example, Ron Cohen led a CDQ team in a dispute regarding whether the Maricopa Association of Governments engaged in an unconstitutional taking of property through its handling of an application for approval of a water reclamation facility. CDQ attorneys have also successfully represented clients against allegations of unconstitutional conduct such as discrimination, retaliation, and the infringement of due process rights, arising from a variety of situations, including an arrest for the violation of a protective order, the termination of employment, and expulsion from a public university. CDQ lawyers have also represented clients in real property disputes involving assertions of regulatory and de facto takings by governmental actors.
