Law students always stand out with their open outlook, challenging viewpoints and general intelligence. The written works they have to submit are also very thought provoking.
Law essay is not about bringing together all the necessary information and presenting it in the body of your essay. It is not a collection of dry juridical facts. Not at all. Law essays are combination of juridical information and student's own point of view (of course well grounded).
You should choose a topic of current importance for your essay to gain the reader's interest. Take pains to structure your essay following all the instructions. Besides, you should reflect most important events of political and social life in your law essay.
For example, if you have a topic on Criminal law, connected with terrorism, then you are sure to write about the imminent threat of terrorism to our society. You can write about the innocent children as victims of terror acts and express your opinion on penalties for it. As a future lawyer you should be greatly interested in the topic you discuss in your essay.
Mind that the professor grading your essay wants to know your personal attitude to the discussed point. If you are able to include your own comments on it and back it up with reasonable evidence, then your essay acquires vigor and interest for the reader. It is no more a cited textbook. The law knowledge is the backbone of your essay; you are just to add your personal opinion to enrich the general contents of your essay.
Your law essay should reflect your erudition, intelligence, creative and research work and your passion for the subject.
