Understanding Self-Defence Law
Self-defence is your legal right to use reasonable force to protect yourself, another person, or property when under threat. This defence is governed by Section 76 of the Criminal Justice & Immigration Act 2008 and Section 3 of the Criminal Law Act 1967.
The law recognises two types: private self-defence (protecting yourself or your property) and public self-defence (preventing a crime from occurring). What makes self-defence powerful is that it's a complete defence - if successful, you'll be found not guilty rather than receiving a reduced sentence.
Necessity of force is judged based on your honest view of the situation, even if you were mistaken about the facts (established in Williams). However, if you're drunk and misjudge the threat level, this won't help your defence (O'Grady case).
Key Point: The jury decides what counts as "reasonable force" by considering the threat level, urgency of the situation, and whether you had other options available.

When Self-Defence Works (and When It Doesn't)
Excessive force will cause your self-defence claim to fail completely - the Clegg case shows that going too far means you'll still be found guilty. The challenge is that there's no exact measurement for "reasonable" - it must be an honest, instinctive response to the immediate threat.
Good news: you don't have to wait to be hit first. Pre-emptive strikes are allowed if you have an "honest and genuine belief" that harm is about to occur (Deana case). There's also no duty to retreat - you're not legally required to run away before defending yourself (Bird case).
You can even prepare for an expected attack (DPP v Stratford), but the threat must be immediate. Property defence has special rules for householders under Section 43 of the Crime and Courts Act 2013 - you can use more force to defend your home, as long as it's not "grossly disproportionate."
Remember: Self-defence is about honest, reasonable responses to genuine threats - the law protects those who genuinely fear for their safety or property.

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

Self-defence law gives you the right to protect yourself, others, and property using reasonable force when facing a threat. It's a complete defence that can lead to a not guilty verdict if successfully argued in court.
