Admissible and Reliable Evidence
Ever wondered why some evidence gets thrown out of court even when it seems important? Admissible evidence must be obtained legally - if police break the law to get it, it can't be used in trial.
Take searching someone's flat without a warrant or using entrapment (tricking suspects into confessing). The Brendan Daccey case shows how this can go wrong - police manipulated someone with learning difficulties into confessing to murder, leading to a wrongful conviction.
You've got the right to silence as a fundamental protection. This means you don't have to answer questions or prove your innocence because you're innocent until proven guilty. However, staying silent about specific things (like possession of a weapon) might make the jury suspicious, unless you've got a believable reason.
Reliable evidence must be credible, authentic and accurate - basically, would the jury believe it? Evidence can't be tampered with or forged. Courts sometimes consider character evidence about defendants (like previous lies or similar crimes), but this is heavily restricted to keep things fair.
Key Point: Evidence rules protect you from unfair treatment whilst ensuring juries get trustworthy information to make their decisions.

Disclosure and Hearsay Evidence
Think it's unfair to be surprised by evidence in court? That's where disclosure of evidence comes in - both sides must share their evidence so everyone can prepare properly.
The prosecution has to show the defence what evidence they plan to use AND what they won't be using. This sounds straightforward, but technology makes it tricky - imagine sorting through thousands of text messages! Sometimes police deliberately hide evidence they think might help the defendant, which is completely wrong.
The Liam Allen case perfectly shows this problem. He was wrongly accused of rape because police only disclosed text messages that seemed to support their case, hiding ones that proved his innocence. When the full evidence came out, the case collapsed.
Hearsay evidence is when someone repeats what they heard someone else say outside court. This is usually banned because the original person isn't under oath and might be lying. However, judges can allow it if the original person has died, is seriously ill, or lives abroad, and it serves justice.
Remember: The Steven Saunders case was groundbreaking - the first time hearsay evidence from a midwife was used to convict someone of controlling behaviour when the victim was too scared to testify.

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.
