Joshua Rozenberg reports from a prison where inmates study legal issues alongside law students from Cambridge University. The academics who launched this ground-breaking project have found that both groups of students benefit by learning together.

Plus, why four doctors have launched a Judicial Review of the Royal College of Physician’s assisted dying poll.

Joshua Rozenberg asks whether new laws are needed to protect online and social media users from abuse?

Plus, in our latest look behind the scenes of courts large and small, we visit an immigration tribunal in central London. Joshua Rozenberg meets applicants who want to stay in Britain and judges who need an encyclopaedic knowledge of world affairs to decide whether they can remain.

We visit a problem-solving court in Coventry. Joshua Rozenberg speaks to judges, social workers and a mother whose drug addiction put her at risk of losing her children.

Behind the scenes at the UK's top court: Joshua Rozenberg talks to staff, officials and the court’s most senior justices. Why do they allow some appeals and refuse even to hear others? How activist are they? And what effect did the Brexit challenge of 2016 have on the reputation of the judiciary?

Judge Alex Calabrese can wield the big stick if he needs to. But peacemakers at the Red Hook Community Justice Centre in Brooklyn often find it more effective to pass round what they call a talking stick. Joshua Rozenberg finds out whether a Native American form of dispute resolution can be transplanted to a deprived corner of New York.

Also, what the new director of public prosecutions for England and Wales thinks about screening jurors before they try rape cases. And one of the BBC team covering the Grenfell Tower Inquiry brings us up to date with the lines of evidence that have emerged so far.

Joshua Rozenberg hears the story of the extraordinary case that rewrote the way America is governed - giving the Supreme Court the power to overrule Congress. He discovers what American prosecutors get up to behind the closed doors of the grand jury room. And he asks whether we should be screening jurors in England and Wales for bias before they are allowed to serve on rape trials.

There is a possibility of a new legal challenge to the tech giants. Early last year, an unknown American law student published a scholarly article in a distinguished journal. Lina Khan argued that competition law – known in the United States as anti-trust law – could be used to rein in the activities of huge enterprises like Amazon. Other lawyers disagree with her reasoning - but the Federal Trade Commission is assessing the arguments. Joshua Rozenberg sounds out opinions in the United States. Also this week: should offences committed in childhood mean a criminal record for life?

Dennis Hutchings, a former soldier charged with attempted murder in Northern Ireland in 1974, says the UK Supreme Court should let him face trial by jury, rather than a hearing at a special court where a judge sits alone. Joshua Rozenberg speaks to Mr Hutchings and his lawyer. And in the first of a series of reports from the US, we investigate whether female lawyers face prejudice in the courtroom - including allegations of using tears to manipulate jurors.

Some police forces are using automated facial recognition technology to pick suspects out of a crowd. But is face mapping a valuable tool in the fight against serious crime or a new threat to our civil liberties? And does it work? Joshua Rozenberg investigates.

Also in this week's programme...

Do body-worn video cameras help police to deal more effectively with domestic violence incidents - or do they make matters worse?

And the mysterious case of the "pernicious weed"...who should pay when the wrong kind of vegetation - such as Japanese knotweed - is found on railway lines?

Does social media pose a threat to criminal justice - and can fair trials be ensured?

In this week's programme, Sir Brian Leveson, head of criminal justice in the courts of England and Wales, tells Joshua Rozenberg that the law needs updating to cope with the growth in social media. And a retired senior judge from Northern Ireland considers whether more needs to be done to protect complainants - and defendants - in sexual assault trials.

Also in this edition of Law in Action: something rather unusual - a private prosecution for fraud.
