"Hawala is a method by which funds can be transferred between people or companies, often across international boundaries. A particular Hawala system will generally be built upon links based upon family, tribe or ethnicity. Transfers of Hawala funds are facilitated through an informal system operated by active Hawalader Brokers, who execute swaps of value or transfers between themselves to settle debts, thus reducing the amount of administrative records and avoiding local controls. The system is built both upon trust and on a history of success. In 2005 the Court of Appeal in Hussain and Ali[2005] EWCA Crim 87 21 & 22 paragraphs described the detail of the process as follows: '21. Hawala banking is an arrangement by which individuals (or intermediaries who have collected money from individuals) deposit money, usually in the form of modest amounts of cash, with a Hawalader in, for example, the UK to be remitted to beneficiaries abroad, commonly in the country from which the remitters' family originate, for example Pakistan. The UK Hawalader will have a Hawala contact in Pakistan who will pay a sum in rupees, at a rate of exchange which may have been agreed with the remitter in advance. The payment will commonly be made more quickly, more cheaply and with less formality than any corresponding service that might be available through the medium of the commercial banks. There is commonly a family relationship between the UK Hawalader and his contact in Pakistan which enables the transaction to be completed with a greater reliance on trust than is necessary in other commercial financial dealings. 22. For ordinary Hawala there must be records to show the identities of the individuals from whom the money had originally been collected in the UK and of those to whom it was ultimately to be paid in Pakistan.' It is not inconsistent with the Hawala process that a Hawaladar or his agent in the UK should collect a stock of cash from different customers and use it to compete entirely separate transactions on behalf of a Pakistani Hawaladar. Hawala banking represents (for the customer) an alternative to the use of the conventional banking system, but a Hawala banker in the UK is subject to exactly the same legal obligations as a conventional banker."
"A person commits an offence if he enters into or becomes concerned in an arrangement which he knows or suspects facilitates (by whatever means) the acquisition, retention, use or control of criminal property by or on behalf of another person."
"He told you that once the system had started it didn't operate differently between 2002 and 2004, though, he said, by 2004 the operation was less active and the amounts that were going through were smaller. He said, 'From the time I started this arrangement with Altaf Khananai I never had any suspicions. He had been introduced by someone I knew. He was a credible businessman. The company of Khanani and Khalia enjoyed an excellent reputation and I thought the cash came from the money service bureaux and I had no reason to doubt this. I never considered or wondered if it came from crime.'"
