In the case of natures of control and what applies when:
Two PSC records, Notified on the same day, identical except for Natures of Control:
1) Ownership of shares – 75% or more
2) Ownership of shares – 75% or more, Ownership of voting rights - 75% or more, Right to appoint and remove directors
In this case I can see from the filings that (1) comes about via the Incorporation (filing history date 17 Aug 2017) and (2) from a notification of a person with significant control (filing history date 25 Aug 2017).
The filings make it clear that the NOCs in (2) currently apply. However, simply looking at the PSC list it wouldn't be clear (to me) which of the above applied. Again - if rules on this (the PSC list at CH) are stated somewhere please let me know.
E.g. it could be:
a) If there is more than one statement relating to a PSC only the latest (Notified on) applies.
b) If more than one statement relating to a PSC has the same Notified on date, the latest is the last one returned in the data from the API (in default sort order).
