Is the intent to discourage *casual* disassembly (given that

be able to argue (in a court of law) that the other party

In the UK, the seals are now designated "Tamper Evident" - which is more

Yes, that is likely the designation, here, as well.

Some can be carefully soaked off with the appropriate solvent and then
replaced after the item has been reassembled - I am not at liberty to
tell you how I know this.

 
Most of the ones that I have encountered have "perforated" adhesives
(for want of a better term).  As you remove the seal, portions of the
adhesive remain behind -- i.e., they adhere more strongly to the
applied surface than to the seal, itself.
