multiple route objects and authorisation

[SerNet Support Lutz Preßler support@localhost]

Hello!

Consider the following (anonymous) example:

inetnum:        192.168.137.0 - 192.168.137.255
netname:        CUSTOMER-PI-NET
descr:          ...
country:        DE
admin-c:        CUSTOMERADMIN-RIPE
tech-c:         TECHC-RIPE
mnt-by:         MAINT-MNT
status:         ASSIGNED PI
mnt-routes:     PROV1-MNT
mnt-domains:    MAINT-MNT
source:         RIPE # Filtered

% Information related to '192.168.137.0/24AS1'
route:          192.168.137.0/24
descr:          ...
origin:         AS1
mnt-by:         PROV1-MNT
source:         RIPE # Filtered


Connectivity for 192.168.137.0/24 shall be switched to PROV2 and
PROV1 may be difficult to contact.

It's possible for MAINT-MNT to add another mnt-routes:

inetnum:        192.168.137.0 - 192.168.137.255
...
mnt-routes:     PROV1-MNT
mnt-routes:     PROV2-MNT
 
But is it possible for PROV2-MNT to add another
route object 192.168.137.0/24AS2 without help from PROV1-MNT?
I read https://www.ripe.net/info/faq/db/route-creation-IP-space-check.html
that it's not possible.
Can MAINT-MNT or CUSTOMERADMIN-RIPE do anything if PROV1-MNT
is unavailable?

Thanks,
  Lutz Pressler
