An arbitration panel yesterday ended a long-simmering dispute between the owner and operator of the Four Seasons Aviara in southern California. Without assigning specific blame to either side, the panel ruled the two companies should end their acrimonious business arrangement.

As a result of the ruling, management of the 329-unit luxury resort in Carlsbad, CA will go to Hyatt Hotels, which will rebrand the property as a Park Hyatt by the end of June. And at least for now, Four Seasons will continue to manage the resort’s 132 timeshare villas.

This corporate version of a no-fault divorce hit the headlines last May when owners Broadreach Capital and Maritz, Wolf & Co. sued Four Seasons, accusing the Canadian hotel firm of alleged “breaches in fiduciary duties” through poor operation and marketing of the resort. In an unusual move in the typically genteel hotel world, the owners tried to forcibly evict Four Seasons from the property and install Dolce Hotels and Resorts as managers. Four Seasons responded by claiming the hotel’s problems were due to the owners’ high debt load on the asset. Negotiations broke down, and a Federal judge ordered the arbitration proceedings.

According to news release, the panel ruled while both sides “contributed to the demise of the business relationship,” Broadreach must pay undisclosed compensation to Four Seasons, which reportedly had a 30-year management contract (starting in 1995) for the hotel.
