14 It has been observed that a plaintiff suing a single defendant, D1, in a building action can have other defendants foisted upon it following joinder upon the application of D1. This puts the plaintiff in a delicate position. It may maintain a lack of interest in the added defendants, making no claim against them, or it may amend its claim to seek relief against them pursuant to s. 131, or otherwise.
15 Each course carries its own risks. If the plaintiff's claim against D1 is an apportionable one and an order for apportionment is made against, say, D1, D2, D3 and D4 in equal shares, the plaintiff who declines to seek relief against D2, D3 and D4 will obtain a judgment for only 25% of its loss against its solitary adversary, D1.
16 If the plaintiff seeks relief against all defendants, judgments in its favour will go against each defendant so that, in aggregate, the plaintiff will have judgment for all of its loss.
17 Difficult questions as to costs arise if D4 is found not to be responsible. The costs of D4 as successful party might be expected to be awarded against the plaintiff if the plaintiff has sought relief against D4. The position would, in all probability, be otherwise if the plaintiff maintained no claim for relief against D4. In that event, it could not to be said that D4 has been successful against the plaintiff. A more realistic analysis may be that D4 has been successful against D1, the party which joined it. I refrain of pursuing the scenario further into the areas of Bullock orders and Sanderson orders.
18 It is sufficient for my purposes that it is important, for costs purposes at least, to determine whether the plaintiff has or has not made a claim against the added defendants. In the present case it seems that, by including paragraph 29E in its counterclaim, Barwon has made a claim against the added defendants, notwithstanding its protestations to the contrary.
19 I interpret its primary position as pleaded as being that it is entitled to recover all of its loss against Aquatec as a claim for a sum due under a building contract. This is not a building action so that no question of apportionment arises. Its alternative claim for damages for defective work is a building action so that it is entitled to judgment against Aquatec only for its share of the responsibility for this loss. In such an event it seeks judgment against each of the added defendants for their share.
