  • Finding the ‚Ä®right words

    In the recent case of Newbury v Sun Microsystems [2013], the defendant argued that an offer to settle proceedings was ‚Äėin principle' only and that a binding contract could not be formed until further terms had been agreed and a formal contract had been signed. It supported this argument by referring to a statement, in the offer letter, that the settlement was to be ‚Äėrecorded in a suitably worded agreement'. ‚Ä©
