Sometimes one of the best roles a criminal lawyer can play is as a trusted ally of their client as they go through what is likely the most difficult period of their life so far. Facing police scrutiny is scary for anyone, but with O’Sullivan Legal behind you – you never have to feel like giving up.



Unbiased professionals

At O’Sullivan Legal, we are unbiased experts who have no judgements or biases as lawyers. That means, at every stage of working with us, you can expect full professionalism and courtesy.

Strategic planning

We take strategy very seriously as having a concrete plan is essential if you want to provide an organised and concise defence. We will sit down with you and plan a strategy for the weeks and months ahead so that you are never in the dark about what happens next.

Help you with police matters

If you are facing your first offence, then facing police scrutiny and intimidation can be scary, and even cause you to say something that incriminates yourself. The police will try to pressure you into admitting guilt any way they can – we are able to supervise police interviews and educate you on your rights.

Excellent listeners

Being a good lawyer isn’t just about advocating, it’s also about listening. This is why we always take the time to let you tell your side of the story with no hesitation – you have full confidentiality with us.

Effective argumentation

Our criminal defence lawyers are highly skilled rhetoricians who know that the way they produce information is just as important as what said information is. They know how to lead a courtroom, question witnesses, and build a robust argument for your defence.

Help with negotiations with police

Many criminal cases end with a plea deal, where the police offer you a lesser punishment if you plead guilty, saving the time and expense of a trial. In these negotiations, we are able to stand by you and ensure you are able to leverage the best possible arrangement.

In-depth research

When you work with our solicitors, they will perform in-depth legal research on past cases similar to yours so that they can cite past decisions to either aid in achieving acquittal, or help you get a reduced sentence.

Punctual and organised

After you engage a solicitor from O’Sullivan Legal, you never have to worry about them arriving late for meetings or failing to return your calls. We are always punctual and attentive with all our clients.

Compassion and understanding

While you aren’t hiring us to be your therapist, it doesn’t mean we are totally cold-blooded (despite the classic lawyer jokes you may have heard). We are your ally during this process and that means supporting to every step of the way.

Criminal Law Firms Sydney

If you have a serious matter with the NSW Police, then some key points to remember are:

  • The Crown bears the onus of proof of guilt for each of the charges you might have been charged with.
  • This burden rests with the Crown and it does not move to you.
  • There is no obligation whatsoever on you to prove any fact or issue in dispute.
  • You do not have to prove your innocence.
  • It is for the Crown to prove your guilt.
  • If you decide to give evidence, you do not have to prove that your version of events is true. In such a case, the Crown must satisfy the trier of fact that the version of events given in the defence case should not be accepted as a version of events that could reasonably be true.
  • The Crown must prove guilt beyond reasonable doubt.
  • If there is any reasonable possibility that you are not guilty, then you must be acquitted.
  • However, the Crown does not have the burden of proving beyond reasonable doubt every single fact that arises from the evidence that is in dispute. Rather, the Crown’s obligation is to prove each element of each charge beyond reasonable doubt.
  • If you give evidence the Crown must satisfy the trier of fact beyond reasonable doubt that that version ought to be rejected as a reasonably possible version of the facts.
  • If the evidence you produce to the trier of fact leaves a reasonable doubt as to whether the Crown has made out its case in respect of any element of any offence, then a verdict of “not guilty” is required in respect of that offence or those offences.
  • If the trier of fact decides that there is a reasonable possibility that the version presented by the defence is true, then the Crown will have failed in its obligation to persuade the trier of fact of guilt beyond reasonable doubt, on that charge.
