Technically, so would any knife where one's fingers obstruct the blade from closing. My Leatherman Squirt is like that.
However:

The argument seems to centre around 'immediate' folding (in order to make it a folding pocketknife), versus a process required before it can be folded (as found with the lock knives in this and similar cases), to establish a difference between a legal pocket-folder and illegal lock-knife.
By this alone, the Micra would be immediately folding.
The argument arises from the generally-accepted assertion that a lockknife is obviously a more effective stabbing weapon if it is locked. Non-locking folding knives present a danger to the user and are thus less likely to be used as stabbing weapons for that reason.
In light of this, while the Micra's handle may prevent the blade from
fully closing immediately, in order to use it as a weapon the offender would have to hold the knife... and in such an event the blade folding would hit his fingers before it could touch the handle anyway, thus upholding the risk mentioned above that mitigates the risk of it being used as a weapon.
Either way, it does not lock like those knives exhibited in the above cases and, from 'fully open', the blade can still freely fold enough to render it an ineffective option for a weapon.
