The problem is that some CCTV footage is still recorded on ageing VHS cassettes. Without having the VHS machines in courts, the footage won't necessarily be able to be played back or used as evidence.
This can lead to cases being delayed or even abandoned.
"It is well known that one of the major obstacles to efficiency in our criminal justice system is the difficulty of storing and sharing at an early stage the vast array of evidence pertaining to cases," said Lady Dorrian.
While they had wanted to keep producing the machines, saying there remained customer demand for them, key components for them were increasingly hard to source.
The SCTS ensured it had ownership of the last batch of the machine for sale in the UK.
A SCTS spokesman said: "The SCTS maintains and upgrades its courtroom technology capability on a regular basis.
"The courts receive evidence in a wide range of formats in both civil and criminal cases from a range of parties, including evidence which has been captured on VHS format.
"Often this is from privately owned CCTV systems. The court needs to be able to present evidence in the format in which parties to a case present it, which is usually the format in which it was recorded," reported the Mirror.
VHS recorders were largely replaced by recordable DVD machines and digiboxes. However, the increase in services where content can be viewed, such as Netflix, Stan and ABC iView, has largely rendered even this new technologies increasingly obsolete.
Japanese company Funai Electric made the world's last video cassette recorder in July.
