Three defendants have been added to a lawsuit filed in 2008 over an alleged conspiracy to defeat Roger Snyder's re-election bid for West Donegal Township supervisor in 2007.

The amended complaint added township supervisors Steve Speers, Charlie Tupper and Nancy Garber as defendants, according to documents filed Monday with U.S. District Court in Philadelphia. Supervisor Clair Hilsher is not named in the suit.

Defendants in the original suit filed Nov. 3, 2008, are Casey Kraus, former chief of Northwest Regional Police Department, and officers Kenneth M. Henry and Randall J. Aument.

Snyder and resident Earl Kean, who served as Snyder's campaign manager, filed the lawsuit claiming the three supervisors and three police officers conspired with "unnamed people" to defeat Snyder in his 2007 re-election bid.

The amended complaint alleges the three supervisors took retaliatory action in January against Snyder for filing the 2008 lawsuit by removing him from seats on the Elizabethtown Area Regional Authority, the Northwest Regional Police Commission and the Northwest Regional Comprehensive Plan Committee.

The suit further alleges the three met in violation of the state's open meetings law, also known as the Sunshine Act, prior to removing him from the positions.

According to newspaper records, the suit accuses Kraus, Henry and Aument of working with "persons unknown" to create a politically explosive environment during the 2007 election and doom Snyder's run as a township supervisor. Snyder, Garber and Keith Murphy ran for two six-year terms. Snyder won re-election after defeating Murphy by 205 votes.

The incident that reportedly prompted the actions that Snyder and Kean allege took place was Snyder's use of township equipment to print campaign fliers for himself and Garber. Snyder said he paid the township for the copies, as he had done in the past.

The suit states that Kraus attempted to pressure four township employees to sign letters of defiant trespass and then had Henry deliver the letters to Snyder and Kean at the township meeting on Nov. 5, 2007, one day before the election. The suit further alleges the letters were designed to create a media incident that would harm Snyder's election goals.

The lawsuit further claims that Aument showed up to the Nov. 5, 2007, township meeting in uniform with "his weapon regalia," something that Snyder and Kean say in the lawsuit never happened at previous meetings.

According to newspaper records, Kraus discussed the trespass issue with the Lancaster County District Attorney's Office and turned it over to the state Ethics Commission. The lawsuit states the disclosure of the "purported ethics violation" was illegal.

The amended complaint also alleges that in February Garber informed Snyder's son, Eric, and Kean that if they did not sign an attendance log they would not be permitted to talk or participate in the meeting, and reportedly no other citizens were treated in this fashion. Both refused to sign. The suit claims the two were singled out in retaliation for Snyder and Kean filing the suit.

• Kean and his wife, Linda, also filed a lawsuit in the U.S. District Court Eastern District of Pennsylvania for alleged harassment and intimidation. Earl asserts he has suffered retaliation for his opposition to a regional police department.

The defendants in the lawsuit include the County of Lancaster, Northwest Lancaster County Regional Police Department, Elizabethtown Borough Police Department, West Donegal Township and Mount Joy Township as well as Elizabethtown Borough police officers Michael Lyons Sr. and Gordon Berlin, Henry, Kraus and up to 10 unspecified "John Does."
