Protections from criminal frauds eg on appeal (10)
I believe the answer is:
safeguards
'protections' is the definition.
(safeguard is a kind of protection)
'criminal frauds eg on appeal' is the wordplay.
'criminal' is an anagram indicator.
'on' is a charade indicator (letters next to each other).
'appeal' becomes 'SA' (old-fashioned abbreviation for sex appeal).
'frauds'+'eg'='fraudseg'
'fraudseg' anagrammed gives 'feguards'.
'feguards' after 'sa' is 'SAFEGUARDS'.
'from' acts as a link.
(Another definition for safeguards that I've seen is " machinery in case something goes wrong".)
