A drunken, belligerent law student who lectured police on the law after being kicked out of a Wollongong hotel has lost her bid to have charges against her dismissed.

"F... off, pig, I'm a lawyer. I got 94 in my UAI and I'm sorry you are so inferior and don't know the law," Morgan Elderfield allegedly told police in the lead-up to her arrest on November 13 last year.

However, the 22-year-old's apparent legal expertise was little help to her yesterday, when she was convicted of a number of charges relating to her booze-fuelled outburst.

Wollongong Local Court heard earlier that Elderfield had gone out with friends to the North Wollongong Hotel and consumed a number of drinks before being asked to leave by security.

Instead of walking out the front as directed, the Wollongong woman kicked up a fuss, throwing a beer over a security guard before sitting on the ground and refusing to leave.
