OK, let's try to read between the lines.
Turner apparently left Calsouth and started working for SCDSL. (Note: I don't know Turner.) Calsouth is a governing body, and various leagues pay Calsouth to act as their governing body. So Turner left a governing body to become employed by a league, which had already left Calsouth.
Calsouth has now hired a lawyer to "investigate" certain claims, citing two particular "allegations;" namely, that (1) Turner and the SCDSL "inappropriately" persuaded clubs to move; and (2) "possible" financial inducements were made to the clubs to change leagues. Calsouth writes that it is "saddened" by its need to partner with its law firm, DLA Piper.
This press release appears to be drafted by Calsouth, and not a law firm. It's wording is stupid in some cases, such as use of the term "misgivings" here: "Cal South has a fiduciary duty to every organization, team, coach, and family involved in the Southern California soccer community to shine a light on the misgivings within the business of youth soccer ..." No lawyer would write that. And I cannot think of a time when Calsouth ever investigated any "misgivings" in any of the 20 or so years that I was a coach licensed by Calsouth. This tells me that Calsouth is acting solely on its own behalf without any real interest in its "fiduciary duty" to others. It lost customers, and therefore money. In my view, the only "duty" it acts on is its duty to its bank balance.
Second, Calsouth is trying to make it look like DLA Piper is going to do an independent "investigation," which is a complete crock of ... well, you know. I believe that CalSouth is hoping that DLA Piper will find a tenable basis for an "interference with contract case. " But in California, employees can leave to work for a competitor pretty much whenever they want to do so, and they can take clients with them, and there is no rule saying that they cannot persuade other clients to leave. The main exception occurs when an employee misappropriates confidential information from his old employer and uses it to take away clients. Here, Calsouth seems to allege that Turner contacted a bunch of club executives and talked them into switching leagues. If he did it while employed by Calsouth, that might be actionable. But if he did it after he left, then my guess is that Calsouth doesn't have a case. First, the SCDSL had already left Calsouth before Turner changed his employment. Second, the contact information for pretty much every club president in Calsouth was not confidential; those numbers were listed on the web pages for pretty much every league, including both CSL and SCDSL (now Socal).
In my view, this presser has the ring of desperation and is mostly meant to save face.
