It’s extremely unlikely that either of the Tates will be tried for their alleged criminal behaviour in either Romania or the UK now.
With the caveat that we don’t know what external pressures Romania were put under from the point the brothers were first arrested, it’s regrettable that they couldn’t get the two in front of a court for over two years.
Had the Romanians got their act together, they would have been convicted (or exonerated) by now and Trump wouldn’t have had this option.
