Recently in Trident Austwide Pty Ltd v Bagcorp Pty Ltd as trustee for the Rico Tea Trust [2024] NSWSC 479 (30 April 2024), Hmelnitsky J said:

41. Trident’s entitlement on account must first be ascertained by reference to the Partnership Agreement which, as I have noted, entitles it to its partnership share of partnership property and to its share of the goodwill of the business. There was no suggestion that I should read this provision as referring only to book values. Given that the pre-emptive provisions of the Partnership Agreement dealing with retirement were not engaged, Trident’s position under the Partnership Agreement would appear to be that it is entitled to an account for its partnership share of the partnership property including goodwill, at market value.
42. Authority generally supports the taking of an account in these circumstances by calculating the outgoing partners aliquot share of the enterprise value as at the date of retirement. In Chia v Ireland, the Court held that the appropriate measure of Dr Ireland’s entitlement on retirement from a medical practice was “her proportionate share in the net proceeds remaining after all the partnership assets have been sold and after payment of the partnership debts and discharging liabilities.” That must be understood as a reference to a notional sale as a going concern, which is how it was understood in Truong v Lam at [28].

In Masson v State of Queensland [2018] QSC 162 (23 July 2018), Henry J said:

[12] Mr Peters concluded Ms Masson was “hypoxic and deprived of oxygen and required oxygen immediately”.^[12] His response to the risk inherent in oxygen deprivation was to ventilate and oxygenate her by the application of a bag valve mask.^[13] The operator of the mask indicated she was difficult to oxygenate.^[14] Mr Peters applied an intravenous cannula into her cubital fossa (elbow pit) to administer intravenous drugs.^[15] One minute after arrival at 22.59 he commenced administering intravenous salbutamol in aliquots (portions) of 250 micrograms.^[16]

               …..

[14] In all, eight aliquots, a total of two milligrams, of salbutamol were progressively administered from 22.59 to 23.20.^[17] This was actually twice the maximum dose of one milligram recommended in the Salbutamol drug data sheet in the Clinical Pharmacological section of the QAS Clinical Practice Manual.^[18] However the plaintiff did not rely upon that as a particular of the alleged negligence.
