The legislation replaces the 1891 framework, which was built around paper-based banking. Its broader definition of official bank records covers paper documents as well as electronic, virtual and cloud storage, allowing newer forms of banking information to be used as court evidence.

For employees, a key safeguard concerns appearances as witnesses, particularly where their bank is not involved as a litigant. Courts will need a specific justification, described as a special cause, and must record that justification before summoning an officer rather than calling staff merely because they hold records.

Such grounds can include questions about whether an entry is accurate, disruption to the system maintaining records, or failure by a bank to comply with a lawful direction. The protection therefore does not remove judicial oversight or excuse banks from meeting legal obligations.

The Act also provides uniform formats for certifying records, with handwritten, electronic or digital signatures permitted. Documents may be submitted on paper or electronically. The changes respond to growing digital banking and cyber fraud, including digital-arrest scams, while seeking to simplify evidence handling and safeguard data. The Centre also has scope to bring other financial businesses under the framework later.
