A federal court sided with Wynn Resorts in a lawsuit which claimed that the Las Vegas casino operator encouraged an Everett landlord to terminate the lease of an auto body shop near its Encore Boston Harbor property.

Judge Richard Stearns approved Wynn Resorts’ motion to dismiss the lawsuit this week. The complaint originally filed in February 2019 by ADH Collision of Boston Inc. claimed that the Las Vegas casino giant pressured its landlord at 36 Mystic St. to file a series of complaints with city inspectors so that he would agree to an early lease termination.

The business sought $3.2 million in damages, claiming intentional interference with advantageous business and contractual relations and violations of the Massachusetts consumer protection law.

The casino giant made a series of offers to buy properties including 36 Mystic St. in 2015 and 2016, and landlord filed a series of complaints with Everett inspectors that prompted them to issue violations and caused the landlord to notify ADH that it had breached its lease terms, the lawsuit stated.

Lawyers for Wynn Resorts argued the suit was “frivolous” and that the plaintiff failed to show any evidence of illegal conduct.

“Wynn simply offered to purchase the parcels and included in its offers a standard clause that the offer was for the parcels free and clear of any tenants or encumbrances,” attorneys Wayne Dennison and Joshua Dunn of Brown Rudnick wrote in a June 3 filing.

 The property remains under ownership by A & R Trust, which originally acquired the property in 1982 for $23,500, according to Middlesex County Registry of Deeds records.

As Wynn was developing the Encore Boston Harbor casino, it also bought up 16.5 acres nearby, which it hopes to lease for development into an entertainment district at a later date.
