The deadline for submissions in response to the government's controversial Communications Data Bill passes on Thursday, with internet rights advocates calling for the government to drop the proposed legislation.
The government first unveiled the document in June, prompting widespread outrage at the 'Snoopers' Charter' proposals. These included plans to force internet service providers (ISPs) to store details of everyone's internet use for up to a year so that police could use it to fight crime and terrorism.
Now, as the consultation draws to a close, these same activists have reiterated their calls for the bill to be canned, urging the public to voice their dissent.
"We urge everyone to submit evidence today," said the executive director of the Open Rights Group, Jim Killock.
"The Home Office should be running a full public consultation. We still don't really know what is proposed, or what evidence the government believes it has. These are dangerous proposals that will come to haunt the coalition should they be pushed through."
Meanwhile, Nick Pickles, director of privacy campaign group Big Brother Watch, warned web users the bill would place onerous monitoring systems on their internet use.
"The Communications Data Bill would make Britain the first and only democratic country to monitor who its citizens are emailing, what websites they read and who they chat to on Facebook," he told V3.
"It would make surveillance the norm for every person in Britain and make available detailed information about our lives to countless public authorities, not to mention those who might seek to access it illegitimately."
He also said the failure of other laws, such as the Regulation of Investigatory Powers Act (RIPA), showed the government needed to vastly improve on its current gathering of digital data, rather than merely bringing in new laws that turned citizens into suspects.
"We should be having a thorough review of the failings in the existing legislation rather than adding further to the legislative mire and diverting billions of pounds away from the police," he said.
"Instead of this deeply illiberal and intrusive legislation, which will still not snare the most severe threats to our security, the focus should be on better understanding how to adapt investigative techniques to the modern world."
Despite these concerns, the government has in the past turned a deaf ear to criticisms of new laws.
Famously, the Digital Economy Act was passed in the wash-up process in 2010, despite widespread criticism of its contents and an embarrassing lack of knowledge on digital issues from most MPs who voted to pass the bill.
