Key legal question
Whether the enforcement request filed on 2012-06-29 was null because it had been lodged to validate the first attachment, later annulled.
Extracted holding
The enforcement request was not null and remained capable of validating the second attachment.
Extracted reasoning
A prior enforcement at the attachment forum can validate a later attachment covering the same claim and the same assets, so long as the enforcement was still valid when the second attachment was executed.
