Certiorari

The procedure through which the U.S. Supreme Court exercises its discretion to review decisions of other courts

Determination of Significance
Once an EAF has been completed for an action, a determination is then made as to whether it "may have" or "will not have a significant adverse impact" on the environment.  If the action may have such impacts, this positive determination (or pos dec) then requires the preparation of an EIS (Environmental Impact Statement).  If the action is determined to "not have any significant adverse impacts," a negative declaration (or neg dec) is issued and the SEQRA review process ends.
En banc

A review of the decision by all of the appellate judges in the 6th Circuit.

Moot
A matter is moot if further legal proceedings with regard to it can have no effect, or events have placed it beyond the reach of the law. Thereby the matter has been deprived of practical significance or rendered purely academic.
Statute of Limitations
A statute of limitations is a statute setting forth the maximum period of time after certain events that legal proceedings based on those events may be begun. The applicable statute of limitations in all of these proceedings was four months from each determination of significance.
Type I, II (or unlisted) Designation
In determining whether an action is subject to SEQRA review, an action must be categorized as a Type I, Type II or Unlisted Action.  A Type II action is one determined not to have a significant impact or otherwise precluded from environmental review under SEQRA.  Type I Actions and Unlisted Actions are required to undergo SEQRA review, beginning with the preparation of an EAF (Environmental Assessment Form).
