Investigations
introduction
We advise clients on a broad spectrum of issues relating to investigations by the CCCS. Upon a dawn-raid or investigation notice issued by the CCCS, we will assist our clients on every step of the way until the CCCS closes the investigation or makes a decision. These include a multitude of matters such as conducting internal investigations on business activities and agreements, interview preparations, drafting responses to CCCS’ notices and queries as well as engaging with the CCCS regarding the investigation. Our approach in such matters is to allow our clients to put their best case forward to the CCCS in an efficient, truthful and complete manner.
We are also equipped to attend to actual dawn raids conducted by the CCCS against our clients within short notice to ensure our client’s interest are protected.
