にあっては

にあっては is used to highlight or emphasize a particular situation or context and state what is especially true or required in that situation.

Compared to にあって, which simply describes circumstances, にあっては adds contrast or emphasis, similar to saying:

“Especially in the case of …”
“When it comes to …”

It is often used to explain rules, attitudes, or expectations that apply specifically under certain conditions.

This grammar is mainly used in formal or written Japanese, such as essays, explanations, and JLPT reading passages.
