"u slučaju povrede nekog od autorskopravnih ovlašćenja koja proizlaze iz moralnog autorskog prava,..."
= ovlašćenja autora po osnovu autorskog prava koja proizilaze iz moralnog autorskog prava
".... author’s prerogatives associated with / derived from his moral right ..."

here "ovlašćenja" means "rights that the author is authorised to claim as part of his moral rights as author", a rather convoluted and misleading way to say "what rights are included in his moral rights as author"

it's similar in meaning to "ovlašćenja carinika / policajaca / stražara na ulazu fabrički krug i sl."

One option is to translate in a convoluted sentence as in the ST, in which case
"ovlašćenja" = "prerogatives"

or make simple with something along the lines
"... in case of infringement of author's moral rights ..."

as in:
"Moral right
Author’s rights enshrine the very strong link existing between authors and their creation as their personal expression by granting the authors moral prerogatives on their works.

Characteristics of moral rights
These rights are directly attached to the author as a person, they are perpetual, inalienable and imprescriptible (art. L.121-1 CPI).
• Perpetual right
...
• Inalienable right
…
• Unseizable right
….
Author’s prerogatives
Several prerogatives are associated with this moral right. The French code of intellectual property (CPI) states that “An author shall enjoy the right to respect for his/her name, authorship and work “(art. L.121-1 CPI).
• Right of Disclosure
…
• Authorship
The regulator authorises any author of a work to associate his/her name with such work. Authors, however, are entitled to remain anonymous or to use a pseudonym.
• Respect for the work’s integrity
…
• Right to withdrawal or reconsider
