After agreeing to mediation in December, Suffolk Construction CEO John Fish and his former development partner Weiner Ventures settled a four-year-old lawsuit over the failure of the 1000 Boylston luxury condominium tower project.

A spokesperson for Weiner Ventures confirmed the settlement of the dispute in which the construction firm CEO and developer traded blame over the collapse of the project on an air rights parcel owned by Massachusetts Department of Transportation. Terms were not disclosed.

The two sides invested approximately $83 million in predevelopment costs while planning the 440,000-square-foot luxury condo tower over the Massachusetts Turnpike near the corner of Boylston Street and Massachusetts Avenue.

In October, the two sides agreed to appear before retired Superior Court Judge Margaret Hinkle for a Dec. 5 mediation section.

Attorneys for the two sides had told a Superior Court judge in August that they were still far apart on a settlement.

Fish joined the development team as a partner after Samuels & Assoc. withdrew on a larger air rights partnership with Weiner Ventures.

The team was unable to obtain construction financing in summer 2019, and Weiner Ventures notified local media that it was canceling the project, according to testimony. Fish scrambled to line up other investors, but the Massachusetts Department of Transportation canceled the development agreement that fall.

Fish’s attorneys blamed Weiner Ventures for delays that caused the estimated project costs to rise $35 million, while Weiner Ventures said Fish failed to deliver on promises to obtain state permits.

The case raised allegations of destroyed evidence after developers Stephen and Adam Weiner deleted texts and emails from their phones related to the case.

The Boston Globe first reported the settlement. Fish’s attorney, Paul Popeo Jr., did not return a message seeking comment.
