28. As a signatory to the ECHR, the Government is under an international law
obligation to implement ECtHR judgments. The judgment requires the
Government to bring forward legislative proposals for Parliament to
consider. It will then be for Parliament to scrutinise and to decide on those
proposals.
29. That is why the Government is publishing three different options for
consideration to a Committee of both Houses for full Parliamentary
scrutiny. "
"Option 3) a ban for all prisoners
39. This option would re-enact the current general ban on prisoner voting,
with some minor changes.
40. All prisoners would be banned from voting if they were serving a custodial
sentence."
