Admitted to practice before the United States Supreme Court and the following United States Court of Appeals: Federal Circuit; D. C. Circuit; 5th Circuit; and 10th Circuit.  In addition, Bill is admitted to practice before the United States District Courts for: the District of Columbia; District of Colorado; and District of New Mexico; as well as the United States Court for Federal Claims, and the Southwest Intertribal Court of Appeals.

Bill’s practice is primarily focused on oil and gas matters, including litigation involving: operating agreements; foreclosure of liens; title issues; contamination from holding tanks; correlative rights; spacing and forced pooling issues; federal Indian law.  Bill also represents oil and gas companies before the Bureau of Land Management, the Colorado Oil and Gas Conservation Commission and the New Mexico Oil Conservation Division, as well before local regulatory bodies.  Bill was involved in the formation of the La Plata County Energy Council in 1996, a nonprofit trade organization that promotes safe and responsible oil and natural gas development in La Plata County.  Bill also practices election law, litigates civil rights actions, including protection of private property rights, and has handled complex products liability cases. 

Bill and Lon Abadie represented an operating company in an access dispute with a private landowner in a case that established the principle in Colorado that an oil and gas lessee has standing to maintain a prescriptive easement claim against a surface owner.  Bill prevailed in a case of first impression before the Colorado Supreme Court that established that the Colorado Constitution recognizes partial regulatory takings.  He has also successfully prosecuted several civil rights cases, including a case that established the rule in the Tenth Circuit that excessive force may occur even when a victim does not suffer any physical contact or injury (unnecessarily deploying a SWAT team and, among other things, pointing a gun at a young child).  In an important campaign finance case, Bill successfully argued before the Tenth Circuit that Colorado’s campaign finance laws violated the right of equal protection under the laws of supporters of independent and minor party candidates forcing the General Assembly to amend Colorado’s campaign finance law.  In addition, Bill has been appointed class counsel in several cases, including a products liability case that resulted in a settlement of more than $300 Million awarded to homeowners who installed a defective radiant heating hose manufactured by The Goodyear Tire & Rubber Company.  Bill began his legal career practicing communications law before the Federal Communications Commission.
