Being a professional means you are required to act in accordance with a code of conduct set by your professional regulatory body. Your code of conduct usually applies not only to your professional work and behaviour but also to your personal behaviour in case it brings your profession into disrepute.
Professional regulators have extensive investigative powers to look into to your performance, health, personal and professional behaviour. In summary, professional regulators are tasked with considering whether your fitness to practise is impaired and if so, what disciplinary or regulatory action should be taken against you.
Similar principles apply to university students who might find their degree course is terminated as a result of allegations of misconduct. Some students even find their applications for registration with a professional regulator are rejected as a result of alleged misconduct while studying or training.
Each regulator and institution has its own set of rules and procedures. How you respond to any investigation can impact its course and its outcome. It is therefore important to take early legal advice from lawyers who specialise in professional discipline and regulation.
