によらず comes from the verb 依る in conjunction with the auxiliary verb ず. It is inherently the negative form of によって, which is used most often to show the agent of a sentence—“by” which/whom something is done, or to show means. As によらず, it may either show that something is “not by…” or that “X” isn't concerned with the situation at hand. Ultimately, its main purpose is to reject dependency. In other words, the Y circumstance is not dependent on an X circumstance.
Nouns that によらず is most likely to follow include those that deal with kind, standards, hope, efforts, goals, etc.
1. 人間の救いは、人間の資質や性格、努力、経験などにはよらず、神様の愛と福音を信じることによって、神の救いに至ることが出来るというものです。
Man’s salvation does not come by a person’s endowments, nature, efforts, or experiences, but by believing in God’s love and His Gospel, one may be able to attain God’s saving grace.
Sentence Note: によらず is very common with religious expressions. This is partly because many religious texts are translated works; however, they do provide perfect context for this expression.

によらず can be seen as によらない at the end of a sentence. This grammatical situation is very indicative of the written language. The grammatical pattern itself is already quite stiff and formal.

（の）いかん can be inserted before either にかかわらず, を問わず, によらず with hardly any change in meaning these patterns. いかん, written as 如何 in 漢字, means “circumstance” as in “how” situation X is. Interestingly enough, いかん can directly attach to nouns, making the particle の completely optional.
～（の）いかんにかかわらず
With にもかかわらず, （の）いかん typically follows words that involve multiple parts or selections. （の）いかん can only be added to nouns. These nouns, naturally, deal with circumstance. The nouns that are best with にかかわらず can be standalone nouns that refer to a single entity (ex. 契約 ＝ Contract). It's also common with nouns created by pairing two things together like 有無 (existence or nonexistence). It is also great with nouns with indeterminate amount of outcomes such as 結果 (results) and 内容 (content). It isn’t, however, used with lists of three or more nouns.
