Just a small correction- hudd usually is used to refer only to those punishments which are prescribed by Islam- stealing of a certain value, fornication and adultery, accusing someone of those without witnesses, etc. In hudd laws strict requirements for witnesses, circumstances of punishment, etc. are all spelled out exactly. This blasphemy law is not a hudd punishment, rather it is from tazir punishments, that is at the discretion of the judge/authority.
So just need to use a different word when explaining it.
