This is really an interesting situation. Please correct me where I may have facts/suppositions wrong.
1) The sysa is the Spokane Youth Sports Authority, which runs more sports than soccer in the city and community of Spokane. It does not include teams/clubs out in the Spokane Valley, which is under the auspices of the Spokane Valley Junior Soccer Association. (I would state the various club names, but they keep changing on me! It used to be Falcons, River City and Express, I believe.)
2) The sysa has a youth soccer system that encompasses U-6 to U-11 under a rec umbrella, and then clubs (Breakers, Shadow, Riverside, Scotties, Sabers, etc.) that play select (district) and Premier/PDL (only the Shadow/Spyders).
3) The sysa is/was a member association of District Six and the WSYSA.
That is what I believe the background is.
Now, why are they sueing and who are they sueing and what is their beef? In the past there was a big turf/recruiting/team transfer battle between sysa and SVJSA that ened up (so it is rumored) in a lawsuit, but that was mediated into a settlement about a decade ago.
If it is a lawsuit about recruitment/transferring of teams or players, I cannot see how going to court could possibly help anyone. Restraint of free trade, freedom of movement, etc. etc. would likely trump any whining about customers being enticed to pay dues to a new company.
Someone in Spokane = preferably someone who can speak in actual sentenances - please let us know what is going on.
