in spite of; regardless of~
Expresses that something happens or is true regardless of a condition or difference.
This pattern means 'regardless of' or 'in spite of'. It shows that a result is not affected by the thing mentioned. You can use it with nouns (like 年齢 (age) or 性別 (gender)) or with a whole clause (like 行くか行かないか (whether to go or not)).
When you use it with a verb, the verb should be in plain form, and it can be either affirmative or negative. For example, するしないに関わらず means 'regardless of whether you do it or not'. With nouns, it is common to see pairs like 好き嫌い (likes and dislikes) or 経験の有無 (experience or not).
This is a fairly formal pattern, often used in written notices, announcements, or speeches. In everyday conversation, you might hear it, but it gives a stiff, official tone. A more casual way is not standard; 〜にかかわらず is a variant of the same form. 〜を問わず is also formal and used in writing.
