British vs American Usage
Differences
In UK law, 'diminished responsibility' is a specific statutory partial defence to murder (Homicide Act 1957, amended). In US law, the concept is often addressed under broader doctrines like 'insanity defence', 'mitigation', or 'mens rea' arguments, though some states have specific statutes using the term.
Connotations
UK: A formal, well-defined legal doctrine. US: May sound more like a general descriptive phrase outside specific jurisdictions that have codified it.
Frequency
More frequent in UK legal contexts. In general US English, it is less common than terms like 'mitigating circumstances' or 'reduced capacity'.
