ROCKLAND, Maine — The owner of a Rockland apartment complex and the company that manages it have asked a state judge to dismiss a lawsuit filed by a 67-year-old tenant who claims his right to own a gun is being violated.

Park Place Associates of Rockland and Stanford Management LLC of Portland acknowledge in their motion to dismiss that they notified tenant Harvey Lembo he was in violation of house rules by having a gun on the premises and that they would initiate the eviction process if he did not comply.

In August, Lembo, who uses a wheelchair, shot and wounded a man he believed had broken into his apartment to steal his prescription medication.

Soon afterward, Lembo received a letter from the apartment management company explaining its policy against guns.

The lawsuit on behalf of Lembo was filed last month in Knox County Unified Court in Rockland, claiming that the property owner and management company were violating his right to possess a gun as stated in both the U.S. and Maine constitutions.

Lembo is being represented in the lawsuit by attorneys Patrick Strawbridge of Boston and David Thompson of Washington, D.C.

Strawbridge said last month that Lembo has received the support of numerous groups, including the National Rifle Association, in his fight to keep a gun in his residence.

Attorney J. William Drury of Waterville, who represents Park Place Associates, and attorneys James Bowie and Hillary Bouchard of Portland, who represent the management company, filed their motion Tuesday requesting that the lawsuit be dismissed. They argue that the simple notification to Lembo that the companies would initiate eviction proceedings if he did not follow house rules was insufficient to trigger the protection under civil rights laws.

They are asking for the plaintiff to pay for court costs, including attorneys fees being incurred by the companies.

Lembo’s lawsuit argues that he is confined to a motorized wheelchair and that he acquired a revolver to protect himself after he had been the victim of four prior burglaries in his apartment on Park Street in Rockland.

“Threatening to evict Mr. Lembo for defending himself clearly violates his constitutional rights,” NRA Maine State Liaison John Hohenwarter said last month when the lawsuit was filed. “Self-defense is a fundamental, God-given right that belongs to every law-abiding American — no matter their tax bracket, zip code or street address. Furthermore, Article 1 Section 16 of the Maine Constitution echoes this sentiment by stating: ‘Every citizen has a right to keep and bear arms and this right shall never be questioned.’”

Lembo used the weapon to shoot Christopher Wildhaber, 46, of Rockland, who Lembo said had broken into his home to steal his medications. Wildhaber was shot in the shoulder and fled the residence before being apprehended by Rockland police in nearby woods.

Wildhaber was taken to Pen Bay Medical Center in Rockport but later was transferred to Maine Medical Center in Portland, where he was treated for his wound before being taken to jail.

Wildhaber initially was charged by police with burglary, theft of medication, attempted theft and three counts of refusing to submit to arrest. A Knox County grand jury indicted him last week for on those same charges.

Wildhaber has been held at the Knox County Jail in Rockland since his arrest.
