19 terror-related offences are added to the scheme to keep families and communities safe.
The scheme which allows victims of crime and the public to challenge sentences handed out by the courts will include a further 19 terror-related offences from today (8 August 2017).
The changes to the Unduly Lenient Sentence (ULS) scheme mean that those found guilty of crimes such as encouraging terrorism, or failing to disclose information about a terrorist attack, could see their sentences increased if victims or the public think the punishment is too soft.
Justice Minister Dominic Raab said:
"We want the most robust sentences for any terrorist crimes and for victims to have every opportunity to see justice delivered.
"This government is determined to keep families and communities safe. This extension sends clear message that we will not tolerate people who help radicalise terrorists or wilfully turn a blind eye to terrorist activity."
The scheme gives anyone the power to ask the Attorney General to review a sentence, who can then decide to refer a case to the Court of Appeal for reconsideration.
The step also fulfils a manifesto pledge to act in this area, helping to protect the public and make sure victims see justice done.
Solicitor General Robert Buckland QC MP said:
"From today, prosecutors and members of the public are able to challenge an additional range of terror-related offences if they think the sentences are unduly lenient.
"Terrorist activity is a direct threat to our way of life. It is vital that crimes of this nature are treated with the utmost seriousness to keep our communities safe."
