Legally, what (if anything) could follow?
The starting point is that once a person has been acquitted of a crime, they cannot be retried for the same crime. (The “double jeopardy” rule)
But there are exceptions.
Part 10 of the Criminal Justice Act 2003 sets out the law legislation.gov.uk/ukpga/2003/44/…
This is where an acquittal resulted from interference with, or intimidation of, a juror or witness.
But the rules are strict.
If these are all satisfied, the court must “certify” as such.
The case then goes to the High Court.
Should there be prosecutions and convictions, I’d expect a retrial to be applied for.
We will simply have to wait and see what happens.
