It's important to understand or remember in all of these circumstances that to the extent that crimes are alleged to have been committed by people who are Libyan citizens or within Libyan territory, Libya as a sovereign country has the primary jurisdiction to deal with those offences. The Rome Statute of the International Criminal Court, in article 17, provides for complementary jurisdiction. The ICC only takes jurisdiction if a state that otherwise has jurisdiction is unable or unwilling to exercise that jurisdiction.
It's probably premature to talk about the ICC in this circumstance until the Libyan authorities, having gone through or going through whatever capacity restoration or development needs to be done, have the opportunity to exercise the jurisdiction that they have over Mr. Gadhafi and his cohorts.
