Considering that the arbitration panel is probably taking weekends off, they've had 67 days to deliberate on the Floyd Landis issue.
I previously said that the Supreme Court doesn't usually take this long to make a decision. They do take this long, and longer in some cases. That said however, their case load is a bit larger than the Landis arbitration panel. The Supreme Court Recent Decisions page shows 75 cases upon which they have issued formal decisions this year, and these are matters of constitutional law. This page says that their caseload is more than 7000 cases on the docket per term.
As best as I can determine, there are only 3 members on Floyd's arbitration panel. This is, as far as we know, the only case that they are deliberating, though I'm sure that they all have full time jobs, families and other commitments that take up their time.
Under the rules of the hearing, the prosecution and the defense were each allowed 25 hours of testimony before the panel. So, 50 hours of material... The panel has had, now, 68 days.
At this point, we may be able to take some comfort in the fact that the longer a jury deliberates, the more likely they are to decide in favor of the defense.
