[5] The relevant principles according to which the discretion as to costs is exercised are not in doubt. The statutory provisions (for costs are the creature of statute[1]) are in s 15 of the Civil Proceedings Act 2011 (Qld) and UCPR 680, 681, 682 and 684. The purpose of costs is compensatory. The width of the power where each party can claim some success is now reflected in UCPR 681 and 684. The word "event" in the former rule is to be read as including the plural "events", so that an order for costs may reflect the success of particular parties in respect of separate events decided in the proceeding.[2] As well, the latter rule refers to making an order for costs in relation to "a particular question in, or a particular part of, a proceeding" whereas the previous comparable rule referred to costs of several "issues", which had a potential confining affect.[3] It is unnecessary to further explore the operation of UCPR 681 and 684 together.
