Once it was necessary to subscribe to (an expensive) series of law reports to read leading judgements soon after they were delivered. While special deals were available to students - it was still a costly business. Now electronic databases are available - and it is no longer necessary to search for the particular book (sometimes in vain! - there were some despicable students who would hide particular volumes - so keeping to themselves a resource all students needed). However, access to a database is expensive if you can't use one through a university or law firm.
The UK Supreme Court now publishes judgements on its website. This is accessible here. A press summary is available in pdf format - as is the full judgement. For those who aspire to be lawyers, it is worth getting into the habit of reading full judgements. Each judge explains his or her reasoning - and a better appreciation of the issues can be gained.
