Approach lighting failure at night

[Lissart]

Mornin'

Reference EU-Ops with the following scenario:

It's night, weather/cloud not sparkling but should be OK. Cat1 ILS and the approach lighting has failed leaving fully serviceable runway edge, threshold wing bars, stop end, PAPIs etc.

What are the legalities of making an approach to this r/w? What if they failed before dispatch or at a time after commencement of the approach? I assume that maybe higher minima might apply and that there might be further constraints if the flight was public transport. Basically, can it be done?

Thanks for the help,
L
