	On 2 May 2024, DCS filed a defamation lawsuit against Stephan Fischer, the creator of AllOffroad 4x4 Adventures TV, in the District Court of Queensland. Fischer had published video reviews between August & December 2023 documenting battery degradation & warranty discrepancies.<ref name="judgment" /> The District Court ruled against DCS on 11 March 2025, finding that DCS was not an "excluded corporation" under section 9 of the ''Defamation Act 2005'' (Qld) & therefore had no standing to sue for defamation. The court found DCS failed on both the employee count test & the associated entity test, citing financial intermingling between DCS & Energy Tech Electronics.<ref name="judgment" />		On 2 May 2024, DCS filed a defamation lawsuit against Stephan Fischer, the creator of AllOffroad 4x4 Adventures TV, in the District Court of Queensland.
