Its broad jurisdiction was based on encroachments of the crown, esp. It was abolished by the Long Parliament in 1641. The aftermath of the fall of the Soviet Union has presented the Star Chamber with both problems and opportunities. Problems, in that the collapse of the old Eagle vs. Evil Empire dialectic caused a dramatic drop in the need for their taxpayer-supported services. What is required for the economic success of the Star Chamber in the post-cold war world is an inconclusive American foreign policy suited to initiating conflicts, but not resolving them.
Many small wars require many small to medium arms, the kind they specialize in.
Likewise, an inconclusive and ineffectual U.S. drug interdiction policy is important to them and their friends in Central and South America and in the former Soviet Union. The Star Chamber is the Maytag of money laundering operations as well, so a friendly Treasury Department helps enormously. Key to this is a manipulatable U.S. President. George Bush was a good friend of the Star Chamber, even when the ex-CIA Director was Vice President under Ronald Reagan. Now I'm not one to believe in conspiracy theories.
