Tony Blair's government has created more than 3,000 new criminal offences during its nine-year tenure, one for almost every day it has been in power.
The astonishing tally brought accusations last night of a "frenzied approach to law-making" that contrasts with falling detection rates and climbing levels of violent crime.
The figures emerged as police chiefs disclosed they were considering asking ministers for a set of new measures to allow them to impose "instant justice" for antisocial behaviour.
The 3,000-plus offences have been driven on to the statute book by an administration that has faced repeated charges of meddling in the everyday lives of citizens, from restricting freedom of speech to planning to issue identity cards to all adults.
In total, the Government has brought in 3,023 offences since May 1997. They comprise 1,169 introduced by primary legislation - debated in Parliament - and 1,854 by secondary legislation such as statutory instruments and orders in council.
Remarkably, Labour is creating offences at twice the rate of the previous Tory administration. During its last nine years in office, under Margaret Thatcher and John Major, fewer than 500 new crimes reached the statute book via primary legislation.
And the rate at which offences are being created is accelerating the longer that Tony Blair remains in Downing Street. In 1998, Labour's first full year in power, 160 new offences passed into legislation, rising to 346 in 2000 and 527 in 2005.
Nick Clegg, the Liberal Democrat home affairs spokesman, who uncovered the figures, said: "Nothing can justify the step change in the number of criminal offences invented by this Government. This provides a devastating insight into the real legacy of nine years of New Labour government - a frenzied approach to law-making, thousands of new offences, an illiberal belief in heavy-handed regulation, an obsession with controlling the minutiae of everyday life.
"The result? A country less free than before, and a marked erosion of the trust which should exist between the Government and the governed."
He said ministers had failed to grasp the simple truth that "weighing down the statute book" with new laws was "no substitute for good government".
Many offences are uncontroversial and will have widespread support, such as tougher penalties for selling contaminated food or against violent crime. But the Government has still managed to produce a surreal list of new offences.
It is now illegal to sell grey squirrels, impersonate a traffic warden or offer Air Traffic Control services without a licence. Creating a nuclear explosion was outlawed in 1998.
Householders who fail to nominate a neighbour to turn off their alarm while they are away from home can be breaking the law. And it is an offence for a ship's captain to be carrying grain unless he has a copy of the International Grain Code on board.
The Home Office, which has produced 60 Bills over a hyperactive nine-year period, is responsible for 430 of the new offences.
The flood of Bills compares with one criminal justice Bill per decade for much of the 20th century and has brought pleas for a period of calm from the department.
Terry Grange, Chief Constable of Dyfed-Powys, has accused the past two home secretaries, Charles Clarke and John Reid, of making policies "on the hoof" in response to media pressure over serious crime problems, foreign offenders and the immigration service.
Lord Ramsbotham, the former chief inspector of prisons, has urged Tony Blair to "shut up" for the sake of stability in the criminal system.
Almost every other part of Whitehall has also found things to outlaw. The Department for Environment, Food and Rural Affairs has brought in 640 new offences, the vast majority through secondary legislation. The Department for Trade and Industry has produced another 592, and the Foreign Office and the Office for the Deputy Prime Minister 277 each.
Each addition swells the enormous number of offences already on the statute book, some dating back to medieval times. Even the Attorney General's office said it had no idea how many existed. A spokeswoman said: "There are thousands and thousands."
Downing Street argued last night that much of the legislation it had inherited needed to be updated. A spokesman said: "Crime has fallen by 35 per cent since Labour came to power precisely because we have given the police and criminal justice system the modern laws they have asked for to tackle crime effectively.
"Among the offences we've modernised are new laws to tackle sex offences, domestic violence, antisocial behaviour and knife and gun crime. Are the Liberal Democrats saying these were a mistake?"
Mr Blair has made clear that he favours an extension of summary justice, and fresh proposals are expected in the autumn.
The Association of Chief Police Officers disclosed yesterday that it was considering asking ministers for powers of instant justice, including the authority to exclude unruly youngsters from town centres and to break up teenage gangs.
Condemning the idea, David Davis, the shadow Home Secretary, said: "We cannot bypass the court system. It is up to the justice system to scrutinise and take judicial decisions, not the police."
Shami Chakrabarti, the director of human rights group Liberty, said the figures demonstrated that politicians were becoming "addicted to law making". She said: "The next time the cry goes up to legislate our way out of a crisis, a deep breath from the Home Office might just be more inspiring than further statutory graffiti."
Enver Solomon, deputy director of the Centre for Crime and Justice Studies at King's College London, said: "It has become a New Labour trademark to criminalise a range of social harms which would be more effectively dealt with away from the clutches of the criminal justice agencies."
