いかんにかかわらず・
This highly formal construction says that a rule, decision, or result remains the same no matter how a particular matter turns out or what its circumstances are.
How it works
いかん here refers to the state, nature, or outcome of the matter named before it. The main clause then states what will happen independently of that variation. This makes the construction especially suitable for rules that must apply consistently.
この制度は、申請理由のいかんにかかわらず、すべての利用者に適用される。
This system applies to all users regardless of the nature of their reason for applying.
AnalyzeLiterally: This system applies to all users without being affected by how the reason for applying stands.
Rules unaffected by a variable
The noun before the construction identifies the variable; the main clause gives the policy that does not change.
