The higher the court, the more arcane the arguments

The arguments used in court can be arcane, particularly when the case is about a narrow technical interpretation. However, sometimes the judgements are about broader principles.

For example, I offer the summary of R v Chaytor and others: http://www.supremecourt.gov.uk/docs/UKSC_2010_0195_ps.pdf where at issue is the limits of parliamentary privilege provided by the Bill of Rights.
