Question juridique clé
Whether the security deposit had to be released after Y. was already serving a prison sentence.
Solution extraite
Yes. Once the accused was in custody serving sentences, the procedural purpose of the security deposit was no longer served and continued retention was disproportionate and unlawful.
Motifs extraits
The deposit serves to secure attendance and surrender for proceedings and sentence execution; that purpose was already achieved by actual imprisonment. No remaining flight risk justified keeping a third party's security in place.
