The Sentencing Council is expected to suspend guidelines which advise judges to consider the lives of offenders from ethnic minority and other backgrounds before deciding on punishment, government sources have told the BBC.
It comes after the government said it would pass an emergency law to override the guidance, which prompted claims of “two-tier justice”.
The guidelines were due to come into effect in England and Wales on Tuesday, after the Sentencing Council refused to reconsider them.
The prime minister said he was “very disappointed” and had “no other option” but to pass a law overruling the body.
But government sources said it would be all but impossible to pass such legislation before Easter.
Conservative shadow justice secretary Robert Jenrick claimed the Sentencing Council had “folded under the pressure” after he had threatened a legal challenge against the guidelines.
The guidelines advise that magistrates and judges get a pre-sentence report – giving further details of an offender’s background – before handing out punishment for someone of an ethnic or faith minority, alongside other groups such as young adults, abuse survivors and pregnant women.
The Sentencing Council, made up of some of the most senior legal figures in England and Wales, said the guidance would address disparities in the punishments meted out by judges.
Official figures show that offenders from ethnic minorities consistently get longer sentences than white offenders for indictable offences.
Speaking to GB News on Monday, the prime minister said the government would bring forward legislation to reverse the new guidelines.
“There’s no other option, so we will do that. We will fast-track it,” he said.
The Ministry of Justice said the legislation would “clarify that guidance relating to sentencing reports should not single out specific cohorts for differential treatment”.
The Sentencing Guidelines (Pre-sentence Reports) Bill will be introduced on Tuesday.
However, it needs to be debated and approved by MPs and peers before it becomes law.
The House of Lords breaks for Easter on Thursday, while MPs break up on 8 April, and Parliament is not due to return until 22 April.
This means there is limited time for the bill to complete its passage.
Justice Secretary Shabana Mahmood said the guidelines “create a justice system where outcomes could be influenced by race, culture or religion”.
“This differential treatment is unacceptable – equality before the law is the backbone of public confidence in our justice system,” she said.
“I will change the law to ensure fairness for all in our courts.”
Some in government believed the law could and should have been rushed through before the Easter break.
Others are understood to have raised concerns that it would be obstructed in the House of Lords, especially by eminent lawyers, if the government were seen to be moving with excessive speed.
Jenrick first raised concerns about the guidelines earlier this month, saying they were biased “against straight white men” and amounted to “two-tier justice”.
In response, Mahmood said she also opposed a “two-tier sentencing approach” and that she “did not stand for any differential treatment before the law”.
The Sentencing Council was established in 2010 to try to ensure consistency in sentencing. Sir Keir, at the time Director of Public Prosecutions, was one of its founding members.
