The government is treating Parliament with "contempt" by rushing through new powers to tackle coronavirus without debate, the Commons Speaker has said.
Sir Lindsay Hoyle said he could not give MPs a vote on getting a bigger say on renewing emergency powers later.
But it was not a decision he had "taken lightly" - and he issued a stern warning to the government to give MPs a chance to debate future policy changes.
His ruling ends the prospect of a backbench Conservative rebellion.
Dozens of Tory MPs were backing an amendment by senior Tory MP Sir Graham Brady calling for future regulations affecting the whole of England only to be introduced if Parliament has the opportunity to debate and vote on them in advance.
In a statement before Prime Minister's Questions, Sir Lindsay said he was unable to select any amendments ahead of a vote on the renewal of the powers to avoid "undermining the rule of law".
MPs are due to vote on a motion that will extend the Coronavirus Act, the emergency legislation passed in March, which grants extensive powers to the authorities to tackle Covid, such as closing schools and stopping mass gatherings.
Sir Lindsay said any amendment to that motion risked creating uncertainty about the legality of the Act, and potentially opened it up to court challenge.
But many of the coronavirus measures introduced since March, such as the mandatory wearing of face masks in shops and the "rule of six" limit on gatherings, have been introduced through regulations linked to an older piece of law.
These regulations - known as statutory instruments - must be approved by Parliament but are often not debated.
Sir Lindsay told MPs: "The way in which the government has exercised its powers to make secondary legislation during this crisis has been totally unsatisfactory.
"All too often important statutory instruments have been published a matter of hours before they come into force and some explanations as to why important measures have come into effect before they can be laid before this House has been unconvincing and shows a total disregard for the House."
He said he was "now looking to the government to rebuild trust with the House not treat it with the contempt it has shown".
He encouraged MPs to table more urgent questions and motions to challenge ministers and make them come to the Commons to explain their actions.
Sounds like compromise IS done btw Govt and rebels with enough in it to avert bigger bust up ... Hancock to give details at despatch box later— Laura Kuenssberg (@bbclaurak) September 30, 2020
BBC political editor Laura Kuenssberg said "all is not well between Downing Street and the Conservative Party backbenches" but a compromise between the two sides was expected to be announced by Health Secretary Matt Hancock in the Commons shortly.
Speaking on Politics Live on BBC Two, she said it was "fascinating" that the Speaker is encouraging urgent questions and debates on Covid-19 restrictions, especially as Sir Lindsay Hoyle is not an "activist speaker" in the way that his predecessor John Bercow was.
A Whitehall source told the BBC there has been "constructive dialogue" between the government and potential rebels over how to handle any future Covid-related regulations, and that "both sides recognise the need to balance proper Parliamentary scrutiny with the government's ability to act swiftly when necessary".
Sir Graham, who is chairman of the influential 1922 Committee of Tory MPs, said he remained hopeful that the government will make concessions.
In a statement, he said: "The Speaker set out his reasons for not selecting any amendments but he also made it clear that he expects the government to ensure proper and timely Parliamentary scrutiny.
"I am hopeful that the government will respond appropriately this afternoon."
Conservative MP Steve Baker, one of those seeking more checks over the government's powers, said he was satisfied with the Speaker's ruling.
"Mr Speaker's decision is entirely reasonable and his statement will reassure all MPs supporting Sir Graham.
"I hope and expect to reach a good compromise with the government shortly so we can advance as one team."
The Commons will vote on whether to renew coronavirus legislation passed at the start of the pandemic in March, which gives the government sweeping powers to act but has to be extended every six months.
At least 16.6 million people in the UK - about one in four people - are subject to local lockdowns - and a growing number of MPs have expressed their concern that the measures are disproportionate even though they have often been requested by local leaders.
MPs are concerned recent interventions - including Wednesday's tightening of restrictions on separate households in the North East of England mixing indoors in public places - have been announced with little warning or debate.
Meanwhile, the Lib Dems said they would vote against extending the Coronavirus Act because of the power it gave ministers to "reduce rights" for carers.
