Thomas v Hollier

The High Court of Australia considered an appeal concerning an "I.O.U." document issued by the respondent, Mr. Hollier, to the appellant, Mr. Thomas. The dispute centred on whether this I.O.U. represented a new contractual obligation or merely an acknowledgment of an existing intercompany debt. The core question was whether the I.O.U. was supported by sufficient consideration to be legally enforceable as a standalone debt.

The High Court was required to determine two primary legal issues. Firstly, whether the I.O.U. document was intended to extinguish the pre-existing intercompany debt and create a new contractual obligation between the parties. Secondly, if it was intended to create a new obligation, whether there was valid consideration to support that new promise.

The Court reasoned that an I.O.U. is generally not a deed and therefore requires consideration to be enforceable as a promise to pay. In this instance, the I.O.U. was issued in circumstances where an intercompany debt already existed. The Court found that the mere acknowledgment of an existing debt, without any new promise or detriment, did not constitute fresh consideration. Therefore, the I.O.U. did not create a new, enforceable contractual obligation separate from the original debt. The appeal was allowed, the judgment of the Supreme Court of New South Wales was set aside, and judgment was entered for the defendant (Mr. Hollier) with costs.
