If the POR occurs in September, then the clock starts for SLI negotiations. If an agreement is reached (so as to avoid M/B arb), a new combined list could be in place by the end of the year. As Clear stated, the APA does not want delays.
Comparing this timeline to Judge Silver's timeline; if she takes more than 3 months to rule, her decision could be largely unenforceable, as a new list would already be in use and USAPA dissolved. This is supposing a ruling for the plaintiffs, which I find highly unlikely.
Ripe, dismissed with prejudice.
Cheers.
