A heated legal dispute between billionaire investor Bill Gross and his tech-entrepreneur neighbor is now in the hands of an Orange County Superior Court judge, as hearings that included allegations of voyeurism and loops of high-decibel sitcom theme songs came to an end Wednesday.

Attorneys representing the respective owners of neighboring ocean-front Laguna Beach mansions on Wednesday both asked Orange County Superior Court Judge Kimberly A. Knill to issue a restraining order limiting what the other party can do on their property, a result of what one of the lawyers referred to as “a neighbor dispute that has gone completely out of proportion.”

Gross, the former Pimco investment fund founder, and former professional tennis player Amy Schwartz, whom Gross described as his life-partner, said they purchased the Laguna Beach property to serve as a private respite to spend summer weekends when they weren’t at their main Newport Beach home.

Their neighbors – former software company executive Mark Towfiq and his wife, Carol Nakahara – said they built their “dream-home” on their property, a place where they could host their extended family.

Instead, both sides say they now feel unsafe in their own homes, accusing the other side of harassment. Depending on whom you ask, the conflict either began with an unpermitted $1 million lawn sculpture and protective netting on the Gross property, or traffic fall-out from a taping of the HBO show “Ballers” on the Towfiq property.

Towfiq and his wife testified that soon after they complained to the city about the sculpture, Gross and Schwartz began playing looped music at high-volume, with the “Gilligan’s Island” theme song being a frequent part of the playlist. They cited a text Gross sent them in response to a request to turn the music down in which he wrote “Peace on all fronts or we will have nightly concerts here, big boy.”

During closing arguments Wednesday, Attorney Chase Scolnick, who is representing Towfiq, said his client had no idea of the “wrath, revenge and harassment he would face.”

“They were furious,” Scolnick said of Gross and Schwartz. “And almost immediately they began a calculated and cruel campaign to intimidate and harass.”

Gross and Schwartz have testified that they were simply listening to music while enjoying nighttime swims in their pool, and said the “Gilligan’s Island” theme became a favorite after they learned the opening of the show was partially filmed near their Newport Beach home. Their attorney alleged that Towfiq’s efforts to photograph and film them was not about documenting noise violations, as Towfiq claimed, but instead a “weird” and “creepy” violation of privacy.

“It is true they play music, they enjoy it, they dance to it,” said Jill Basinger, an attorney representing Gross and Schwartz. “The purpose of their home is the outdoor living. It is an open floor plan. they listen to music, but there is no evidence the music is loud.”

Towfiq’s attorneys specifically asked the judge for a three-year restraining order barring Gross and Schwartz from playing music at a level that violates city code and to not play music on outdoor speakers when no one is in their yard. Gross and Schwartz’s attorneys are seeking an order that would bar Towfiq from using an iPhone or cameras to record Gross or Schwartz on their properties.

Judge Knill said she needed time to consider the arguments, and ordered the parties to return to court on Dec. 23 for her ruling.
