Grossly Offensive vs Indecent: Untangling Section 127 Legal Test

Section 127(1) of the Communications Act 2003 uses four words to define prohibited content: "grossly offensive or of an indecent, obscene or menacing character." They are not synonyms. Each has a distinct legal meaning, and a message only needs to fall into one category.

Disclaimer: General information, not legal advice.

Grossly Offensive — The Most Used

Lord Bingham defined it in DPP v Collins [2006]: outrage, shock, or disgust to a reasonable person in an open and just multi-racial society. It takes "mere offensiveness" off the table — "grossly" does real work. Racist abuse is the paradigm. The reasonable person is objective, not the recipient.

Indecent and Obscene

Indecent covers sexual impropriety and lewdness — content that is sexually inappropriate without necessarily being obscene. Obscene tracks the Obscene Publications Act 1959 standard: content tending to "deprave and corrupt." Rarely used for online speech — the OSA and CPA 2026 have largely superseded it.

Menacing — Chambers and Context

Conveying a threat. But in Chambers v DPP [2012], the High Court held that context determines whether a message is menacing. Chambers tweeted about blowing up an airport — literally menacing — but no reasonable person reading it in context would treat it as genuine. Context is baked into the test.
