If you are studying law and using one of our legal databases, Westlaw, you may come across the abbreviation 'WLUK'.
WLUK are Westlaw's own neutral citations and are not a published case series or law report. As noted in the current Practice Direction you should cite a published series in preference, e.g. The Law Reports, the Weekly Law Reports, the All England Law Reports or a specialist series. If this is the only version of the case available then please note the difference in detail:
Stream v Environment Agency  4 WLUK 397
 is the year the case was heard
4 is the month of the hearing (not the volume)
WLUK is Westlaw United Kingdom
397 is a sequential number given to the case by Westlaw (not a page number)
If you are submitting work to Newcastle Law School for marking then you should not cite WLUK.
