In a July 29 final judgment in a high-profile pipeline dispute, 298th District Judge Emily G. Tobolowsky of Dallas ordered Enterprise Product Partners to pay Energy Transfer Partners as much as $620 million if postjudgment interest accrues until 2017.

Beyond just the high dollar award, the case is generating interest because it raises the question of whether a company can participate in a preliminary discussion of joint ventures of any sort and still avoid partnership obligations under Texas law.
