Our short answer is: it depends.
In all honesty, having a criminal record will make it more difficult for you to convince us that you are a good fit for the law school– and for the legal profession.
But there are exceptions. If what you did was the result of bad decision making as a teenager and you have now grown more mature and wiser as a result of that youthful transgression– we can understand that as well. It depends on what you did, and how you justify your breaches of the law to us.
But given the nature of the legal profession, and the importance of lawyers being seen as ethical and law-abiding individuals, we would need to see a very convincing explanation not only of what happened, but also of how you see yourself as an ethical and upstanding member of the legal profession moving forward.
