DSU Case Law Paper

This is a must read for any construction broker, underwriter or claims professional dealing with DSU

A decision was handed down in the Supreme Court of NSW in 2017. It has some interesting findings relating to construction business interruption (most commonly known as a DSU – Delay in Start-Up –but also referred to as ALOP – Advanced Loss of Profits, and ACL – Advance Consequential Loss).

In this instance it was called a ‘Dept Servicing Standing Charges Insurance Policy’ (DSSC). For all intents and purposes, it is structured in the same manner as a typical DSU policy.
