Natasha Myler
Wilson Tighe is the best criminal lawyer in Sydney. I highly recommended him not only for his highly competence in laws but also for his kindness and humanity. We thank him a lot for his help in our matter.

Ruen Motto
Used O'Brien solicitors for both of my criminal law cases which they managed to get all charges dismissed when I was looking down the barrel of 18 months jail. Then even more impressively ran my civil claim vs the police and I got a very good outcome and substantial pay out. Easy to talk to and actually listened and took my opinion into consideration which is a first. Highly recommend!

Jonah Yahud Islam
Dedicated, diligent and efficient! I had the good luck of being represented by O'Brien lawyers resulting in a favourable outcome. If you are looking for lawyers to represent you in a difficult criminal case, then look no further.

Danny Lane
The quality of service provided far exceeded my expectations. The elegance and professionalism in which this firm conducts itself is to be admired. They don't treat you as just another client. I cannot recommend them enough for criminal and civil matters as they excel at both. Special thank you to Peter & Elle, I will never forget the impact this outcome has had on my life.

K Wong
I recently had to engage the firm to represent me in a criminal matter. I initially liaised with Tim Rayner (criminal paralegal) who assisted with handling my case, whom I found to be professional and always responsive. Elliot Rowe (criminal solicitor) was assigned as my legal counsel. I highly commend Elliot for his consistently methodical and prudent handling of my case and his calm and patient demeanour, which provided some measure of reassurance to me during a particularly distressing period in my life.

Chris
I found myself facing the criminal justice system for the first (and hopefully only) time. Contacted O'Brien solicitors based on the number of positive reviews and was put through to Elliot. His patience with me was outstanding, helping me navigate and understand what lay ahead. Never felt rushed. He was very objective and not judgemental in any way. Gave me plenty of options which allowed me to arrive at a fair outcome. At sentencing he spent the whole day with me in court. I consider Elliot to be more an ally not just a lawyer. Can't recommend Elliot highly enough.

Ingrid Kelly
Me and my family have been working with O'Brien Criminal and Civil Solicitors in regards to representing us for criminal defence in two cases. In both cases our solicitor Wilson Tighe was professional, transparent and provided us with professional advice throughout the procedures. I highly recommend their services to others.

Blake Hopkinson
Sidnie was thorough, informative and well versed. Her dedication and attention to detail, and ability to force the truth to be seen, were the reason I got the result that I should have. Highly recommended her and this firm.

O'Brien Criminal and Civil Solicitors is hands down the most reliable, understanding and professional firm I have dealt with.

FAQ’s on Sexual Assault Law
How do I fight sexual assault charges?
Fighting sexual assault charges requires a strategic legal defence.
Key steps include:
- Engaging an experienced criminal defence lawyer immediately.
- Maintaining your right to silence and not speaking to police without legal advice
- Gathering evidence to support your case, such as alibis, text messages, or CCTV footage.
- Identifying and interviewing potential witnesses.
- Scrutinising the prosecution's evidence for inconsistencies or procedural errors.
- Exploring possible defences like consent or mistaken identity.
- Negotiating with prosecutors to reduce or drop charges where appropriate.
- Preparing thoroughly for trial if charges proceed
Our skilled sexual assault lawyers can guide you through this process and build the strongest possible defence strategy tailored to your specific case.
What is the best defense to sexual assault?
The best defence to sexual assault charges depends on the specific circumstances of each case. Some common and potentially effective defences include:
Consent: Proving the sexual activity was consensual.
Mistaken identity: Demonstrating you were not the perpetrator.
Alibi: Showing you were elsewhere when the alleged assault occurred.
Lack of evidence: Highlighting insufficient proof to establish guilt beyond reasonable doubt.
Mental impairment: Arguing you lacked capacity to form criminal intent.
Honest and reasonable belief in consent: Showing you genuinely believed consent was given.
Your lawyer will assess the details of your case to determine the most appropriate and effective defence strategy. A combination of defences may be used to create reasonable doubt about your guilt.
What is the lowest charge of sexual assault?
In Australia, sexual assault charges vary in severity, with the lowest level typically being indecent assault. This involves unwanted touching of a sexual nature without the victim's consent. Specific offences and terminology can differ between states and territories. For example, in New South Wales:
- Indecent assault (s 61L Crimes Act 1900) carries a maximum penalty of 5 years imprisonment
- Sexual touching (s 61KC) is a similar offence with a maximum 5 year sentence
While these are considered "lower level" sexual offences compared to aggravated sexual assault or rape, they still carry serious penalties and potential registration as a sex offender. Even minor sexual assault charges require robust legal defence to protect your rights and future.
What percentage of sexual assault cases are taken to court?
In Australia, only a small percentage of sexual assault cases make it to court. While exact figures vary, studies suggest that less than 20% of reported sexual assaults result in charges being laid, and an even smaller proportion proceed to trial. Factors contributing to this low rate include:
- Victims choosing not to pursue charges
- Insufficient evidence to proceed
- Cases being dropped during the investigation phase
- Plea bargains resulting in guilty pleas without trial
It's important to note that many sexual assaults go unreported, further lowering the overall percentage of cases that reach court. This highlights the complex nature of sexual assault cases and the challenges in prosecuting them effectively.
What is good evidence in a sexual assault case?
Strong evidence in a sexual assault case can include:
- Victim testimony: A clear, consistent account of the incident
- Physical evidence: DNA samples, injuries, or torn clothing
- Medical records: Documenting injuries or sexual contact
- Witness statements: From people who saw the incident or its aftermath
- Electronic evidence: Text messages, emails, or social media posts
- CCTV footage: Showing the victim and accused together
- Expert testimony: From psychologists or forensic specialists
- Prior similar acts: Demonstrating a pattern of behaviour by the accused
The most compelling cases often combine multiple types of evidence. However, even with limited physical evidence, a credible victim statement can be powerful. Each piece of evidence helps build a comprehensive picture for the court to consider.
How are sexual assault cases handled?
Sexual assault cases in Australia are handled with sensitivity and care, following a structured process:
- Reporting: Victims can report to police or seek medical attention first
- Investigation: Police gather evidence and interview relevant parties
- Charging: If sufficient evidence exists, charges are laid against the accused
- Legal proceedings: The case moves through the court system
- Trial: If not resolved earlier, the case is heard before a judge and jury
- Sentencing: If found guilty, the offender is sentenced
Throughout this process, victims have access to support services and legal advice. Special provisions may be made to protect vulnerable witnesses during court proceedings. The handling of these cases aims to balance the rights of the accused with the need to support victims and secure justice. Experienced sexual assault lawyers play a crucial role in navigating this complex process.
What role do expert witnesses play in sexual assault trials?
Expert witnesses play crucial roles in sexual assault trials by educating jurors about complex topics and dispelling myths. They explain medical and forensic evidence, providing context for physical findings and DNA analysis. Mental health professionals offer insights into victim psychology, helping jurors understand trauma-related behaviors. Experts assist in credibility assessments by explaining factors like delayed reporting and memory effects of trauma. In civil cases, they can establish damages suffered by victims. Their specialized knowledge helps judges and juries navigate the complexities of sexual assault cases, aiding in the interpretation of evidence and victim testimony. Expert witnesses contribute significantly to achieving just outcomes by bridging the gap between technical information and lay understanding in the courtroom.
