Don’t step on Elvis Presley’s blue suede shoes. And don’t you go messing with his Lincoln Continental, either.

A number of artifacts that belonged to The King are being illegally held by a resort in Las Vegas, according to a new lawsuit.

In the suit, filed in district court in Clark County, Nevada, on Monday, Elvis Presley Enterprises claims that a number of Presley artifacts are being held by Westgate Las Vegas Resort & Casino.

According to the suit, in January 2015, Westgate entered into an agreement for “a new exhibition featuring artifacts never before displayed outside of Gracelend, and live entertainment shows that celebrated the life and legacy of Elvis Presley.”

The artifacts include high school yearbooks, Presley’s first gold album, a 1957 Harley Davidson motorcycle, a 1962 Lincoln Continental, a 1971 Stutz Blackhawk, jewelry and stage wear, the lawsuit alleges.

Things went south, the lawsuit claims, when Westgate and Exhibit A Circle — the company that Westgate entered into the agreement with — got into a dispute, with each side claiming that the other had breached the agreement.

“In an effort to gain leverage in its dispute with Exhibit A Circle, Westgate decided to take unlawful possession” of the items, the lawsuit alleges.

Elvis Presley Enterprises also claims that Westgate “forcibly removed all employees, who were charged with protecting the Artifacts, from the Westgate and seized EPE’s property,” and also cut off access to security video that would show what happened to the items.

Westgate has refused to return the property, the lawsuit alleges.
