Oh you have to admire the late Denning for his colourful language and the way he sought to achive justice and fairness in particularly 'hard' cases, my oh my, did he love old ladies. Scarman was also a great Judge, escpecillay how he fostered community relations during the Brixton riots in the early 80s.
Erm..sorry what was the question again? Oh dictionaries, yeah, well most lazy people will just google the terms and about 90% of the time the definitions are right, but remember law is an esoterical subject and laymans terms will mean something completely different to the budding lawyer. I would recommend the Oxford Dictionary of Law, as someone else has also just suggested.
