Maclin "Mac" P. Davis, Jr.

For over 60 years, clients have depended upon Mac Davis to guide them through the litigation process and advocate for their interests. Waller proudly recognizes that Mac is the "Davis" in Waller Lansden Dortch & Davis, LLP. Representing both individuals and companies, and a Certified Civil Trial Specialist in Tennessee, Mac has been involved in a number of historic cases including:

  • Kidd v. McCanless, which ultimately led to the U.S. Supreme Court decision in Baker V. Carr that forced the Tennessee legislature to reapportion itself as required by the Tennessee Constitution
  • Jack Cole Co. v. MacFarland, in which the Tennessee Supreme Court held that a state income tax on earnings is unconstitutional

A devout supporter of the Tennessee Constitution, the rule of law, and the foundations of a representative democracy, Mac's political career in public office was significantly impacted in 1955, when he stood up to party leaders in defense of his oath to uphold and support the constitution of the state. This characteristic commitment to abide an oath and serve those who have entrusted their voice to him has carried forward and underpinned Mac's robust career.

He advises young lawyers to give all matters careful thought, craft sound logical arguments, and cite to authority. This measured, organized approach to a client's given issue has been rewarded by success in the courtroom as well as client relationships that have spanned decades.

Throughout his career, clients from a variety of industries—from music to manufacturing—have relied on Mac to handle their business and individual disputes.  His experience covers a broad spectrum of practice areas such as:

  • Antitrust
  • Constitutional law
  • Election law
  • Family Law
  • Personal injury
  • Real estate
  • Securities

Up Close

In college Mac was on varsity tennis, football, basketball, wrestling and swimming teams. He coached Vanderbilt's wrestling team for a year.

Mac played competitive tennis until he aged out of the bracket system! Now, in his eighties, Mac only dabbles in tennis and spends his free time playing clarinet and tenor saxophone with his wife. They are in a small band led by his wife and they regularly perform for nursing and retirement homes.

He loves horses and farming and was active in breeding and raising horses for many years. He is also a Life Master in duplicate bridge playing. He claims he doesn't play much bridge as he used to because he "just can't be up all night playing cards anymore."
