Israel has always seen implementing civil law in the Palestinian Territories as implicitly annexing the Palestinian Territories. The implications of annexing the Palestinian Territories would be that Israel would be compelled to grant the Palestinians citizenship in Israel and this would effectively make Israel another Arab State similar to Lebanon. When Israel annexed the Golan Heights to bring it under civil law, citizenship was offered to the Syrian Druze who lived there. However, the Syrian Druze were a small population who did not threaten the Jewish majority of Israel. In order to preserve its primarily Jewish identity, Israel has decided to leave the West Bank under martial law.
Additionally, by leaving the territory consistently under martial law, Israel demonstrates that it evinces a serious intent about the possibility of returning the territory to a Palestinian State. This is because a martial system does not create a strong infrastucture.

Nobody was "given" the Golan Heights in 1981. Israel conquered the Golan Heights from Syria in 1967 and repelled a Syrian invasion to retake the Golan Heights in 1973. By the end of the Arab-Israeli population of 1973, the Arab population of the Golan Heights and its strategic value was immense. Therefore, in 1981, Prime Minister Menachem Begin decided to annex the territory of the Golan Heights to the Israel. This has been seen by most international observers as a violation of UNSC Resolution 242 and 338 which requires that Israel return the Golan Heights to Syria in exchange for peace, not to acquire it. Israel has responded by saying that it fully intends to return the territory to Syria should a peace treaty be struck, but it sees no reason why it has to leave the Golan Heights under military administration pending such a resolution as opposed to a civilian one.
Golan Heights
Syria
The Golan Heights is administered by the Israeli government due to UNSC Resolutions 242 & 338/339 - the armistices of 1967 and 1973 between Israel and Syria among others. However, the annexation of the Golan Heights to Israel and its incorporation into the Northern District of Israel in 1981 is considered illegal in international law.
The answer you are likely looking for is: ISRAEL. It is a little more complex though.The Negev Desert is entirely within the borders of the State of Israel. However, the Golan Heights is a more complex issue. The Golan Heights is Syrian territory that is currently under legal Israeli Occupation (pursuant to UNSC Resolution 242). It is generally understood that when Israel and Syria sign a peace treaty that the Golan Heights will revert to Syrian ownership.
