It's clear that a cleric can't cast spells with an alignment descriptor opposed to his deity's (so a chaotic good cleric can't cast evil spells nor lawful spells). However, it's not stated anywhere whether these spells are still in their spell list even though they can't cast them, nor does it say anywhere whether they can cast those spells from wands or scrolls (unlike for wizards' specialization schools). I haven't found anything in FAQs or errata to clarify this.
If it's the case that spells are still on their spell list even though they can't cast them, then a cleric would be able to use spell trigger items such as wands to cast those spells — even though I don't think their deity will like this.
