The Stakes

Terrorist attacks
rise and fall.

And the world's turmoil is mounting again.

When bombs explode, ships are sunk, planes hijacked, and automatic weapons emptied on innocents — the losses are incomprehensible and the quest for justice seems futile.

There may be no more complex challenge for a law firm than securing real justice for families, businesses, and governments after a terrorist attack. There are no simple ways to sue terrorists or those who fed their hatred.

You focus on healing. We'll focus on the fight.

When terrorists strike,

Marc Asks:

01Who was behind this?

02Who do I need on our team?

03What national and international laws apply?

04Which countries and courts can decide the lawsuit?

And while victimized individuals, businesses, and governments are trying to catch their breath — the assets and insurance proceeds they assume will be there to collect are already being depleted by powerful entities, even before the first tears have dried.
