(CNN)Kellie Meir has waited two years to see the man accused of causing her son's death face trial.
Danny Meir, the oldest of her six children, was 22 when he was killed in a collision between his motorbike and a car in Stockton-on-Tees, a market town in northeast England, in July 2018.
The driver of the car, a man in his early 60s, denies causing Meir's death by careless or inconsiderate driving. He was originally due to stand trial last month, but the case has been delayed until March next year, because of the coronavirus pandemic.
The UK locked down on March 23 in an attempt to slow the spread of Covid-19, and while most courts in England and Wales have since reopened, many trials are now subject to lengthy delays, leaving victims and their families in limbo and many defendants -- who remain innocent until proven guilty -- in custody.
Kellie Meir said she first heard of the change to her son's case in June, when friends shared local news articles about the decision on social media.
"That's the worst thing -- we had to read it on Facebook," she told CNN. "Nobody told us. We didn't have a letter. [I] just opened up Facebook and saw his picture all over the place."
Meir said her son was a great motorcycle enthusiast. "I know he was [on his motorbike] when he died, but he loved that thing, from such a young age."
Danny's sudden death left his mother, four younger brothers, younger sister, long-term girlfriend and grandparents devastated. "My mum took it particularly hard [because] they were very close," Meir added.
"It's been two years now, and it'll be three by [the time of the trial.] We can't move on with our lives, we haven't got closure," she said.
'Backlog on backlog'
Trial by jury is a cornerstone of democratic legal systems around the world, especially those based on English common law -- also known as Anglo-American law.
But seating 12 strangers side-by-side in a courtroom for days or even weeks is impractical in these socially-distanced times.
Most criminal cases in England and Wales begin in magistrates' courts, which handle less serious offenses. Following the coronavirus lockdown, the backlog in these courts stands at a record high of 483,678 cases -- up from 406,610 cases earlier this year, according to the British government.
Meanwhile the Crown courts, where more serious cases are heard, face a backlog of 40,526 outstanding cases as of the week ending May 24, according to preliminary data from the British government. That's up from a pre-coronavirus caseload of 39,214, though not as high as a peak of 55,000 cases recorded in 2014.
Lawyers working in the court system in England and Wales criticized the mounting caseload -- which they say is the result of years of underinvestment, cuts and court closures -- long before the pandemic. Coronavirus has only exacerbated the situation.
For victims and their families, the additional delays caused by Covid-19 have made an already stressful situation unbearable.
"It's not just the delay, it's everything around it," said Alex Mayes, external affairs manager at rights group Victim Support. "Before, victims were feeling anxious. Now they have added anxiety around coronavirus itself."
Penelope Gibbs, an ex-magistrate and the founder of NGO Transform Justice, agrees. "It's going to be backlog on backlog, and the problem is in human terms," Gibbs, an advocate for the rights of defendants being held in custody, told CNN.
"The concern is that those on remand are innocent until and if they are proven guilty," she said. "They may well be acquitted and they are losing their liberty when they may well be innocent. For that to go on for months threatens human rights."
"What I fear is that people on remand may change their plea ... from not guilty to guilty. In some cases they may then be released from prison," she added.
And experts say some cases which have been postponed may end up never going to trial because of the lengthy delays.
"The quality of evidence declines over time," veteran British barrister Michael Wolkind told CNN. "There will be certain cases where the victim won't be able to bear the further wait and withdraws. And [there will be] smaller cases where the prosecuting authorities will drop [charges]."
The socially distanced court
There are 77 crown court centers in England and Wales that can host a trial by jury. Fifty-four have reopened since the UK's lockdown was eased, according to the Ministry of Justice, but distancing measures mean many of the courts that are open still have limited capacity for trials. In some courts, rooms required for the trial are rendered useless because of their size.
CNN spoke to lawyers involved in trials who were concerned about the court estate in England and Wales, and its suitability for social distancing.
Michael Auty is a barrister and Queen's Counsel -- a title awarded by the British monarch to particularly respected advocates. Auty has seen many trials delayed because of the pandemic, including that of his client Magdalena Kissova.
Kissova, 47, is charged with murdering a 67-year-old man in Derby, in England's Midlands, in February. She denies the charge. Kissova has been held in custody since her arrest -- her trial was due to begin later this month, but delays caused by the pandemic mean it has been pushed back until October.
"We didn't know if Derby Crown Court was going to be suitable for dealing with jury trials or not," Auty told CNN. "We couldn't carry out the changes [needed] to spread the jury out physically. And there are a host of other things -- the jury have to walk through lots of narrow passages, and their retiring room can't accommodate social distancing. It was not built for a world where that was necessary."
"You couldn't begin to contemplate socially distanced trials," in Derby's modern court building, Auty said. "We could possibly accommodate social distancing in the courtroom itself, beyond that it would be impossible."
The realities of a return to a full trial schedule are a worry for many lawyers.
"I think it's quite scary," Danielle Manson, a junior barrister based in London, told CNN. "I don't feel confident or comfortable about going back to work. The courts estate is crumbling -- and that was before Covid-19."
The UK's opposition Labour Party believes a long-term lack of investment in the legal system has worsened the current crisis in the courts.
"The justice system has been brought to its knees by a decade of austerity that cut funding to the Ministry of Justice by a quarter in real terms," David Lammy, the shadow justice secretary, told CNN in a statement.
"The result of these cuts is vi
