Questions & Answers about В отсутствие кадастрового инженера межевание и согласование границ отменили.

What does в отсутствие mean here?

It means in the absence of or with ... absent.

So В отсутствие кадастрового инженера gives the circumstance under which the action happened: the cadastral engineer was not present.

This expression is fairly formal and is common in official, legal, and administrative language. In less formal Russian, you might more often see something like когда не было кадастрового инженера or без кадастрового инженера depending on the exact meaning.

Why is кадастрового инженера in the genitive?

Because the noun отсутствие normally takes the genitive:
отсутствие кого? чего? = the absence of whom? of what?

So:

• кадастровый инженер = dictionary form
• кадастрового инженера = genitive singular

Both words change because кадастровый is an adjective modifying инженер, so it must agree with it in case, number, and gender.

What case is межевание in?

Here межевание is in the accusative singular because it is the direct object of отменили.

However, for an inanimate neuter noun like межевание, the nominative and accusative forms are identical. So the form looks the same either way.

In this sentence, you understand it as accusative from the syntax and meaning: it is something that got canceled.
