A lawyer for the son and one-time heir-apparent of late Libyan dictator Moammar Gadhafi is warning the International Criminal Court that its reputation will be damaged if it allows Libya to put him on trial.

Melinda Taylor, one of Seif al-Islam Gadhafi's court-funded defense lawyers, told judges that any trial in Libya will be "not motivated by a desire for justice but a desire for revenge."

Taylor spoke Wednesday at a hearing that will ultimately decide whether Seif al-Islam is tried in his homeland — where he could face the death penalty — or at the International Criminal Court in The Hague, where the maximum sentence is life imprisonment.

Seif al-Islam has been indicted by ICC prosecutors, but is detained in Libya, whose new rulers want to try him.
