A few years back, the Northwoods league sued a player who left for the Cape.
They did not attempt to obtain a TRO, if I remember correctly. Rather, they sued the player and received a judgment against the player for something like $15,000 as damages.
While I sure don't know the precise laws that would govern for the CPL, it is generally required that the moving party establish that it will be irreparably harmed to obtain a TRO.
That can be a pretty hard standard to establish.
Thus, it could be that the CPL could have had a better pathway seeking breach of contract and damages as the Northwoods did.
Without knowing the specifics, I can understand the CPL might not receive the TRO but still could have a viable contract.
As I posted earlier, based on our discussions with GM's and owners in the NECBL, I can certainly appreciate why a team or league would want to enforce its contract, if it is a valid one that can be enforced. It was for the Northwoods league and one player learned a tough lesson from that process.
