The treaty is being argued as one-sided as it allows the US to extradite UK citizens and others for offenses committed against US law even though the alleged offence may have been committed in the UK - outside the realm of US law.
The US has a much larger number of extraditions from the UK than the UK has from the US which further tips the unbalance in favor of the United States, and there is the added concern that UK citizens expected to cover the cost of the legal aid privately, as their entitlement to UK legal aid becomes negligent.
Cases that are currently being debated are those of Richard O'Dwyer - 23-year old student charged in the US for breaking its copyright laws; and Christopher Tappin - a 64 year old golfer who is the victim of entrapment; and Gary McKinnon - a computer hacker who was searching for proof of UFOs online.
None of these UK citizens have ever even been to the US, and it is doubtful whether they are committing any crime according to UK law. Nevertheless, they are all at risk of being extradited to the US in the near future.
David Cameron and Nick Clegg came into office with the promise of changing this Act because it is unfairly balanced against UK citizens. Why has nothing been done yet?
