Especially David, your clarifications (also under others' proposed answers) made the difference.... would award you the points if I could, but you didn't 'compete' so when 24 hrs up, will give 2 pts to Michel, who actually submitted 'substance'

Ici, dans un document apparemment à usage juridique, chaque mot a son sens, et sa raison d'être.
Je partage le point de vue de David: "ainsi" se réfère effectivement à tout ou partie du point N°1, et je ne crois pas qu'il faille le faire disparaître. Mais le mot "et" peut être destiné pour sa part à clarifier et à articuler entre eux sans confusion, la référence en question (peut être un point de méthode), et le contenu même ("la substance": voir par exemple Google avec une recherche sur "en substance" et "terme juridique") de la plainte, ou du grief.
Il me semble donc préférable de n'en laisser tomber aucun.

Your clarification helped a lot.... I don't have to worry too much about 'ainsi at' then - many thanks!

I think that 'ainsi' actually refers back to the first point. It is 'ainsi' in the sense of 'de cette façon', i.e. 'in this way'. The 'et' is used to introduce the essence of what is being said. What seems to be being said is: 'In this way, the substance of your challenge is ...". The 'et' is the superfluous element in English. 'En substance' is simply 'the substance/gist' of what is being said.

is a "tic" of formal written FR which can often be dropped from the EN; and the "et" is more or less automatic between two adverbial expressions, so once the "ainsi" goes, it disappears. I don't think "ainsi" is adding any meaning here.
